You might think that Rust is only meant to be used for complex system development, or that it should be used where security is the number one concern. Thinking of using it forweb development might sound to you like huge overkill. We already have proven web-oriented languages that have worked until now, such as PHP or JavaScript, right?

This is far from true. Many projects use the web as their platform and for them, it’s sometimes more important to be able to receive a lot of traffic without investing in expensive servers rather than using legacy technologies, especially in new products. This is where Rust comes in handy. Thanks to its speed and some really well thought out web-oriented frameworks, Rust performs even better than the legacy web programming languages. In this tutorial, we’ll see how Rust can be used for Web Development.

This article is an extract from Rust High Performance, authored by Iban Eguia Moraza.

Rust is even trying to replace some of the JavaScript on the client side of applications, since Rust can compile to WebAssembly, making it extremely powerful for heavy client-side web workloads.

Creating extremely efficient web templates

We have seen that Rust is a really efficient language and metaprogramming allows for the creation of even more efficient code. Rust has great templating language support, such as Handlebars and Tera. Rust’s Handlebars implementation is much faster than the JavaScript implementation, while Tera is a template engine created for Rust based on Jinja2.

In both cases, you define a template file and then you use Rust to parse it. Even though this will be reasonable for most web development, in some cases, it might be slower than pure Rust alternatives. This is where the Maud crate comes in. We will see how it works and how it achieves orders of magnitude faster performance than its counterparts.

To use Maud, you will need nightly Rust, since it uses procedural macros. As we saw in previous chapters, if you are using rustup you can simply run rustup override set nightly. Then, you will need to add Maud to your Cargo.toml file in the [dependencies] section:

[dependencies]
maud = "0.17.2

Maud brings an html!{} procedural macro that enables you to write HTML in Rust. You will, therefore, need to import the necessary crate and macro in your main.rs or lib.rs file, as you will see in the following code. Remember to also add the procedural macro feature at the beginning of the crate:

#![feature(proc_macro)]
extern crate maud;
use maud::html;

You will now be able to use the html!{} macro in your main() function. This macro will return a Markup object, which you can then convert to a String or return to Rocket or Iron for your website implementation (you will need to use the relevant Maud features in that case). Let’s see what a short template implementation looks like:

fn main() {
    use maud::PreEscaped;
let user_name = "FooBar";
let markup = html! {
(PreEscaped(""))
html {
head {
title { "Test website" }
meta charset="UTF-8";
}
body {
header {
nav {
ul {
li { "Home" }
li { "Contact Us" }
}
}
}
main {
h1 { "Welcome to our test template!" }
p { "Hello, " (user_name) "!" }
}
footer {
p { "Copyright © 2017 - someone" }
}
}
}
};
println!("{}", markup.into_string());
}

It seems like a complex template, but it contains just the basic information a new website should have. We first add a doctype, making sure it will not escape the content (that is what the PreEscaped is for) and then we start the HTML document with two parts: the head and the body. In the head, we add the required title and the charset meta element to tell the browser that we will be using UTF-8.

Then, the body contains the three usual sections, even though this can, of course, be modified. One header, one main section, and one footer. I added some example information in each of the sections and showed you how to add a dynamic variable in the main section inside a paragraph.

The interesting syntax here is that you can create elements with attributes, such as the meta element, even without content, by finishing it early with a semicolon. You can use any HTML tag and add variables. The generated code will be escaped, except if you ask for non-escaped data, and it will be minified so that it occupies the least space when being transmitted.

Inside the parentheses, you can call any function or variable that returns a type that implements the Display trait and you can even add any Rust code if you add braces around it, with the last statement returning a Display element. This works on attributes too.

This gets processed at compile time, so that at runtime it will only need to perform the minimum possible amount of work, making it extremely efficient. And not only that; the template will be typesafe thanks to Rust’s compile-time guarantees, so you won’t forget to close a tag or an attribute.

Connecting with a database

If we want to use SQL/relational databases in Rust, there is no other crate to think about than Diesel. If you need access to NoSQL databases such as Redis or MongoDB, you will also find proper crates, but since the most used databases are relational databases, we will check Diesel here.

Diesel makes working with MySQL/MariaDB, PostgreSQL, and SQLite very easy by providing a great ORM and typesafe query builder. It prevents all potential SQL injections at compile time, but is still extremely fast. In fact, it’s usually faster than using prepared statements, due to the way it manages connections to databases. Without entering into technical details, we will check how this stable framework works.

The development of Diesel has been impressive and it’s already working in stable Rust. It even has a stable 1.x version, so let’s check how we can map a simple table. Diesel comes with a command-line interface program, which makes it much easier to use. To install it, run cargo install diesel_cli. Note that, by default, this will try to install it forPostgreSQL, MariaDB/MySQL, and SQLite.

For this short tutorial, you need to have SQLite 3 development files installed, but if you want to avoid installing all MariaDB/MySQL or PostgreSQL files, you should run the following command:

cargo install --no-default-features --features sqlite diesel_cli

Then, since we will be using SQLite for our short test, add a file named .env to the current directory, with the following content:

DATABASE_URL=test.sqlite

We can now run diesel setup and diesel migration generate initial_schema. This will create the test.sqlite SQLite database and a migrations folder, with the first empty initial schema migration. Let’s add this to the initial schema up.sql file:

CREATE TABLE 'users' (
  'username' TEXT NOT NULL PRIMARY KEY,
  'password' TEXT NOT NULL,
  'email' TEXT UNIQUE
);

In its counterpart down.sql file, we will need to drop the created table:

DROP TABLE `users`;

Then, we can execute diesel migration run and check that everything went smoothly. We can execute diesel migration redo to check that the rollback and recreation worked properly. We can now start using the ORM. We will need to add diesel, diesel_infer_schema, and dotenv to our Cargo.toml. The dotenv crate will read the .env file to generate the environment variables. If you want to avoid using all the MariaDB/MySQL or PostgreSQL features, you will need to configure diesel for it:

[dependencies]
dotenv = "0.10.1"
[dependencies.diesel]
version = "1.1.1"
default-features = false
features = ["sqlite"]

[dependencies.diesel_infer_schema]
version = "1.1.0"
default-features = false
features = ["sqlite"]

Let’s now create a structure that we will be able to use to retrieve data from the database. We will also need some boilerplate code to make everything work:

#[macro_use]
extern crate diesel;
#[macro_use]
extern crate diesel_infer_schema;
extern crate dotenv;
use diesel::prelude::*;
use diesel::sqlite::SqliteConnection;
use dotenv::dotenv;
use std::env;
#[derive(Debug, Queryable)]
struct User {
username: String,
password: String,
email: Option,
}

fn establish_connection() -> SqliteConnection {
dotenv().ok();
let database_url = env::var("DATABASE_URL")
.expect("DATABASE_URL must be set");
SqliteConnection::establish(&database_url)
.expect(&format!("error connecting to {}", database_url))
}

mod schema {
infer_schema!("dotenv:DATABASE_URL");
}

Here, the establish_connection() function will call dotenv() so that the variables in the .env file get to the environment, and then it uses that DATABASE_URL variable to establish the connection with the SQLite database and returns the handle.

The schema module will contain the schema of the database. The infer_schema!() macro will get the DATABASE_URL variable and connect to the database at compile time to generate the schema. Make sure you run all the migrations before compiling.

We can now develop a small main() function with the basics to list all of the users from the database:

fn main() {
    use schema::users::dsl::*;
let connection = establish_connection();
let all_users = users
.load::(&connection)
.expect("error loading users");

println!("{:?}", all_users);
}
This will just load all of the users from the database into a list. Notice the use statement at the beginning of the function. This retrieves the required information from the schema for the users table so that we can then call users.load().

As you can see in the guides at diesel.rs, you can also generate Insertable objects, which might not have some of the fields with default values, and you can perform complex queries by filtering the results in the same way you would write a SELECT statement.

Creating a complete web server

There are multiple web frameworks for Rust. Some of them work in stable Rust, such as Iron and Nickel Frameworks, and some don’t, such as Rocket. We will talk about the latter since, even if it forces you to use the latest nightly branch, it’s so much more powerful than the rest that it really makes no sense to use any of the others if you have the option to use Rust nightly.

Using Diesel with Rocket, apart from the funny wordplay joke, works seamlessly. You will probably be using the two of them together, but in this section, we will learn how to create a small Rocket server without any further complexity. There are some boilerplate code implementations that add a database, cache, OAuth, templating, response compression, JavaScript minification, and SASS minification to the website, such as my Rust web template in GitHub if you need to start developing a real-life Rust web application.

Rocket trades that nightly instability, which will break your code more often than not, for simplicity and performance. Developing a Rocket application is really easy and the performance of the results is astonishing. It’s even faster than using some other, seemingly simpler frameworks, and of course, it’s much faster than most of the frameworks in other languages. So, how does it feel to develop a Rocket application?

We start by adding the latest rocket and rocket_codegen crates to our Cargo.toml file and adding a nightly override to our current directory by running rustup override set nightly. The rocket crate contains all the code to run the server, while the rocket_codegen crate is actually a compiler plugin that modifies the language to adapt it for web development. We can now write the default Hello, world! Rocket example:

#![feature(plugin)]
#![plugin(rocket_codegen)]
extern crate rocket;

#[get("/")]
fn index() -> &'static str {
"Hello, world!"
}

fn main() {
rocket::ignite().mount("/", routes![index]).launch();
}

In this example, we can see how we ask Rust to let us use plugins to then import the rocket_codegen plugin. This will enable us to use attributes such as #[get] or #[post] with request information that will generate boilerplate code when compiled, leaving our code fairly simple for our development. Also, note that this code has been checked with Rocket 0.3 and it might fail in a future version, since the library is not stable yet.

In this case, you can see that the index() function will respond to any GET request with a base URL. This can be modified to accept only certain URLs or to get the path of something from the URL. You can also have overlapping routes with different priorities so that if one is not taken for a request guard, the next will be tried.

And, talking about request guards, you can create objects that can be generated when processing a request that will only let the request process a given function if they are properly built. This means that you can, for example, create a User object that will get generated by checking the cookies in the request and comparing them in a Redis database, only allowing the execution of the function for logged-in users. This easily prevents many logic flaws.

The main() function ignites the Rocket and mounts the index route at /. This means that you can have multiple routes with the same path mounted at different route paths and they do not need to know about the whole path in the URL. In the end, it will launch the Rocket server and if you run it with cargo run, it will show the following:

If you go to the URL, you will see the Hello, World! message. Rocket is highly configurable. It has a rocket_contrib crate which offers templates and further features, and you can create responders to add GZip compression to responses. You can also create your own error responders when an error occurs.

You can also configure the behavior of Rocket by using the Rocket.toml file and environment variables. As you can see in this last output, it is running in development mode, which adds some debugging information. You can configure different behaviors for staging and production modes and make them perform faster. Also, make sure that you compile the code in --release mode in production.

Future releases also look promising. Rocket will implement native CSRF and XSS prevention, which, in theory, should prevent all XSS and CSRF attacks at compile time. It will also make further customizations to the engine possible.

The right IDE or a Text editor (Source Code Editor) is always very helpful during coding. It’ll help you be faster, more accurate and ultimately more productive. With autocomplete, line indentation and syntax highlighting features, IDEs speed up and organize the coding process. Getting the right IDE does make a difference. So here are some options to consider:

NetBeans

NetBeans IDE is FREE, open source, multilingual (English, Brazilian Portuguese, Japanese, Russian, and Simplified Chinese) and easy-to-use. Its editor does line-indentation, highlights code syntactically, permits easy refactoring It provides a set of tools tailored for Java, PHP, HTML5/JavaScript, especially for Node.js, KnockoutJS, and AngularJS. There have been added support for more languages and due to its extensibility, other languages can be added.

Atom IDE

This is a text editor that’s modern and customizable up to the point that you can call it “hackable”. It runs on Electron, a well-known framework for building cross-platform apps using web technologies. Features include code navigation features such as outlining views, going to definitions and finding all references. In addition to all that, there is hover-to-reveal information, diagnostics (errors and warnings) and document formatting.

Atom comes packed with a package manager, where the users can search and install new packages, or create theirs. To add to the awesomeness, there are also multiple UI and syntax themes. Atom can be used on OS X, Windows and Linux.

Visual Studio Code

This is the brainchild of Microsoft. It is a lightweight but powerful source code editor. It goes beyond syntax highlighting and auto-complete with IntelliSense, which provides smart completions based on variable types, function definitions, and imported modules. The piece of software comes jam-packed with features supporting many web development languages, including but not limited to, JavaScript, TypeScript, Python, PHP, and Node.js.

A code can be debugged right from the editor. Launch or attach to your running apps and debug with breakpoints, call stacks, and an interactive console. VS Code is available for the popular OS out there; Windows, Mac, and Linux.

WebStorm

This IDE with intelligent code completion, on-the-fly error detection, powerful navigation and refactoring for JavaScript, TypeScript, stylesheet languages, and the most popular frameworks. You can debug your client-side and Node.js apps with ease in the IDE – put breakpoints right in the source code, explore the call stack and variables, set watches, and use the interactive console. Use WebStorm as simple unified UI to work with Git, GitHub, Mercurial, and other Version Control Systems. Commit files, review changes and resolve conflicts with a visual diff/merge tool right in the IDE.

Brackets

Brackets is a modern, open source text editor that understands web design. This IDE is lightweight, powerful and modern. It blends visual tools into the editor so you get the right amount of help when you want it without getting in the way of your creative process. Instead of jumping between file tabs, Brackets lets you open a window into the code you care about most. With the live preview feature, get a real-time connection to your browser and make changes to the code and you’ll instantly see those changes on screen.

PhpStorm

Concerning Php as a programming language, this is the go-to choice. It provides the best code completion, refactorings, on-the-fly error prevention, and more. PhpStorm is perfect for working with Symfony, Drupal, WordPress, Zend Framework, Laravel, Magento, Joomla!, CakePHP, Yii, and other frameworks. In addition to all the other common features available on other IDEs, phpstorm comes with an autocomplete feature capable of completing classes, methods, variable names etc.

It makes the most of the cutting edge front-end technologies, such as HTML5, CSS, Sass, Less, Stylus, CoffeeScript, TypeScript, Emmet, and JavaScript, with refactorings, debugging and unit testing available. Changes can immediately be seen in the browser thanks to Live Edit. As the icing on the cake, it comes integrated with Git as well as other version control software.

Komodo IDE

This is a powerful editor with autocomplete, refactoring and other smart features. It supports dozens of languages including Python, PHP, Go, Perl, Ruby, NodeJS, HTML, CSS, JavaScript and so much more. It is extensible, and as such, more add-ons can be added.

Cisco is moving rapidly toward its ultimate goal of making SD-WAN features ubiquitous across its communication products, promising to boost network performance and reliability of distributed branches and cloud services.

The company this week took a giant step that direction by adding Viptela SD-WAN technology to the IOS XE software that runs its core ISR/ASR routers. Over a million of ISR/ASR edge routers, such as the ISR models 1000, 4000 and ASR 5000 are in use by organizations worldwide.

The release of Cisco IOS XE provides an instant upgrade path for creating cloud-controlled SD-WAN fabrics to connect distributed offices, people, devices and applications operating on the installed base, wrote Anand Oswal, senior vice president of  network engineering in a blog post about the upgrade.

The software includes support for vManage, the cloud-based dashboard built by Viptela that lets users bring up SD-WAN resources and segment resources on the fly.  Cisco acquired the SD-WAN company for $610 million last summer. Earlier this year Cisco added Viptela’s vAnaytics technology to its SD-WAN software to help enterprises identify the stress points and necessary policy or bandwidth changes that might be needed across an SD-WAN.

“Cisco adding SD-WAN capabilities to its ISR/ASR router portfolio is a significant industry milestone in and of itself, as this will allow a large number of enterprise IT shops to benefit from upgrading their existing Cisco-based WANs,” Rohit Mehra, vice president, network infrastructure research at the International Data Corp. said. “And mind you, these are software upgrades that will enable network managers to rapidly move to an agile network environment with improved security and an improved user experience for public cloud/SaaS applications.”

Oswald wrote that Cisco SD-WAN on edge routers builds a secure virtual IP fabric by combining routing, segmentation, security, policy and orchestration.

“It eliminates backhauling from branches to headquarters to access SaaS applications, improving application performance and experience for a distributed and mobile workforce. For example, at the branch-level, you can define a performance policy for Cloud SaaS Onramps to maintain a level of QoS for Office 356 performance and assign a real-time streaming policy for unified communications,” Oswald wrote.

Driving the need for better SD-WAN security and connectivity features is the huge push in cloud computing resources, said Kiran Ghodgaonkar, Cisco senior manager of enterprise marketing.  “With the increased use of multi-cloud services especially, the WAN is really becoming the backbone of the enterprise.”

Lowering costs by not having customers buy new hardware and by easily supporting lower cost connectivity, either via the Internet, Ethernet or LTE is another use case of SD-WAN, Ghodgaonkar said. “Users have diverse workload environments be they mobile or cloud and SD-WAN helps bring those environments closer together.”

The XE SD-WAN upgrade is the second phase of Viptela’s integration into Cisco’s SD-WAN plans. In the first phase, Cisco supported and invested in the overall Viptela SD-WAN package, including the Viptela vEdge routers.

Phase 3 of the integration will see Viptela’s package completely integrated with Cisco’s DNA Center.  Introduced last summer as the heart of its Intent Based Networking initiative, Cisco DNA Center features automation capabilities, assurance setting, fabric provisioning and policy-based segmentation for enterprise networks.

Most recently Cisco said it was opening up the network controller, assurance, automation and analytics system to the community of developers looking to take the next step in network programming. The general idea is to bulk up the the usefulness of DNA Center for the larger world of third-party and customer-application developers.

“Customers have seen value with DNA Center and its security/policy and service assurance attributes that leverage network and applications-based ML/AI. That said, with SD-WAN by itself providing several benefits to existing WAN environments, customers will not need to wait for DNA center integration, although seeing that integration ultimately happen will of course be ideal for Cisco customers,” IDC’s Mehra said.

While this announcement significantly boosts Cisco’s SD-WAN offering and capabilities, challenges remain. Mehra said.

“The ongoing market transformation of the last three-plus years has provided an opportunity to several new vendor and SP-led solutions, and this competitive landscape will not get lighter any time soon. And with service providers looking at the upcoming virtualized branch opportunity with SD-WAN as the beachhead, Cisco will need to stay focused and stay on top of its differentiation strategy for its enterprise customers,” Mehra said.

If you’re experiencing performance issues with your PC, then it’s time to get your system back in shape. Here are five utilities that can clean and tune up Windows in no time at all.

Over time, a once-sprightly PC can begin to slow down under the weight of various programs, files, and downloads that could do with streamlining. These tasks can be attempted manually, but there are plenty of dedicated apps that will do the job for you instead. We’ve gathered together some of our favourite PC cleaning and optimisation apps that should be running on your system right now.

Ashampoo WinOptimizer 2018

Price: £19.99 / US$29.99 per year

  • Download WinOptimizerWinOptimizer is an easy place to start, as not only does it offer plenty of features, but they’re accessible via a 1-click optimisation button that scurries off and checks how your PC performance can be improved.The app de-clutters your hard drive, removes junk files, repairs program shortcuts, fixes Registry errors, and clears out your browsing history and cache. There’s also the option to securely delete sensitive data, or add password protection and encryption instead.

    For those who want to dig deeper there’s detailed analysis of the operating system and modules that can help improve things like boot times and internet connection speeds.

    IOLO System Mechanic

    Price: £30 / US$39.99 per year

    • Download IOLO System MechanicIOLO has a number of optimisation products available for Windows PCs, including security apps, drive scrubbers, password managers, and System Mechanic. The latter is a great piece of software that provides a quick way to get your machine back in tip-top condition.This app employs something it calls LiveBoost technology, which aims to ensure that the CPU, RAM, and hard drive are not overused by aggressive programs. This can give PCs a decent performance improvement, especially if you have resource-hogging software.

      DriveSense is there to monitor the physical attributes of your HD, and can predict if a crash is on the horizon, while the Core Data Recalibrator searches for any potential operating system issues that could become a problem.

      The app also has an All-in-one PC Cleanup PowerTool that automatically removes anything cluttering up your browsers, chat programs, or hard drives.

      System Mechanic is a comprehensive suite, with too many features to mention here.

      SlimCleaner Plus

      Price: Free (£23 / US$29.97 per year for Premium version)

      • Download SlimCleaner PlusIf you don’t want to shell out for optimisation software, then SlimCleaner Plus has a free tier that can still help boost performance on your PC. Admittedly the features are minimal, with it sticking mainly to speeding up startup times by restricting the apps that are loaded when you first turn on your machine.With the paid-for version you’ll have access to tools such as an SSD optimiser that defrags the drive to keep it sharp, and the 1-click scan which searches your entire machine for issues, then provides easy ways to remove them.

        The free version can tidy things up a little, but you’ll want Premium to see significant gains in speed.

        AVG TuneUp

        Price: £34.99 / US$49.99

In the recent report entitled, “100 Data and Analytics Predictions Through 2022,” Gartner analysts offer their views on how data management and analytics trends will evolve over the next five years, and how those trends will impact software development. The report was prepared by analysts Douglas Laney, Guido De Simoni, Rick Greenwald, Cindi Howson, Ankush Jain, Valerie Logan and Alan Duncan.

Application development predictions

Gartner analysts broke out their predictions in the area of software to two main themes—application development and enterprise application software. Four trends will dominate application development, they say.

Virtual codevelopers

“By 2022, at least 40 percent of new application development (AD) projects will have virtual AI co-developers on their teams,” Gartner says.

AI-enabled test set optimizers

“By 2022, 40 percent of AD projects will use AI-enabled test set optimizers that build, maintain, run and optimize test assets,” according to the Gartner report.

Hosted AI services

“By 2022, 30 percent of AD projects will incorporate hosted AI services; fewer than 5 percent will build their own AI models,” Gartner analysts predict.

Event-driven business process management

“By 2022, 50 percent of digital business technology platform projects will connect events to business outcomes using event-driven intelligent business process management suite (iBPMS)-oriented frameworks,” Gartner says.

Enterprise application software predictions

“The enterprise application market is again reinventing itself, headlined by the use of AI, conversational platforms and the exploitation of business network data. Technology business unit leaders need to prepare for new monetization tactics and new competitors through 2022,” the Gartner analysts say. They offered the following three predictions in this area.

Artificial intelligence and recruiting

“By 2021, 30 percent of high-volume recruiting activities (sourcing, screening, shortlisting and candidate interaction) will be done without human intervention, using innovative applications based on AI and data as a service (DaaS),” Gartner says.

Ubiquitous intelligent applications

“By 2022, ‘intelligent’ applications will be ubiquitous, but their usage for managing complex and custom processes will be less than 5 percent,” Gartner predicts.

Real-time analytics

“Between 2016 and 2019, spending on real-time analytics will grow three times faster than spending on non-real-time analytics,” the Gartner analysts predict.

The Java Development Kit (JDK) is one of three core technology packages used in Java programming, along with the JVM (Java Virtual Machine) and the JRE (Java Runtime Environment). It’s important to differentiate between these three technologies, as well as understanding how they’re connected:

  • The JVM is the Java platform component that executes programs.
  • The JRE is the on-disk part of Java that creates the JVM.
  • The JDK allows developers to create Java programs that can be executed and run by the JVM and JRE.

Developers new to Java often confuse the Java Development Kit and the Java Runtime Environment. The distinction is that the JDK is a package of tools for developing Java-based software, whereas the JRE is a package of tools for running Java code.

The JRE can be used as a standalone component to simply run Java programs, but it’s also part of the JDK. The JDK requires a JRE because running Java programs is part of developing them.

Figure 1 shows how the JDK fits into the Java application development lifecycle.

Figure 1. High-level view of the JDK

Just as we did with my recent introduction to the Java Virtual Machine, let’s consider the technical and everyday definitions of the JDK:

  • Technical definition: The JDK is an implementation of the Java platform specification, including compiler and class libraries.
  • Everyday definition: The JDK is a software package you download in order to create Java-based applications.

Get started with the JDK

Getting Java setup in your development environment is as easy as downloading a JDK and adding it to your classpath. When you download your JDK, you will need to select the version of Java you want to use. Java 8 is the version most commonly in use, but as of this writing Java 10 is the newest release. Java maintains backward compatibility, so we’ll just download the latest release.

JDK packages

In addition to choosing your Java version, you will also need to select a Java package. Packages are Java Development Kits that are targeted for different types of development. The available packages are Java Enterprise Edition (Java EE), Java Standard Edition (Java SE), and Java Mobile Edition (Java ME).

Novice developers are sometimes unsure which package is correct for their project. Generally, each JDK version contains Java SE. If you download Java EE or Java ME, you will get the standard edition with it. For example, Jave EE is the standard platform with additional tools useful for enterprise application development such as Enterprise JavaBeans or support for Object Relational Mapping.

It’s also not hard to switch to a different JDK in the future if you find you need to. Don’t worry too much about choosing the correct Java version and JDK package when you are just starting out.

Downloading the JDK

We’ll stick with Java SE for this tutorial, so that we can focus on the core JDK classes and technologies. To download the Java SE JDK, visit Oracle’s official download page. You’ll see the various JDK packages available, as shown in Figure 2.

Before you select the Java SE download, take a minute to look at the other options. There’s a lot cooking in the Java kitchen!

Cybersecurity researchers at the Georgia Institute of Technology have helped close a security vulnerability that could have allowed hackers to steal encryption keys from a popular security package by briefly listening in on unintended “side channel” signals from smartphones.

The attack, which was reported to software developers before it was publicized, took advantage of programming that was, ironically, designed to provide better security. The attack used intercepted electromagnetic signals from the phones that could have been analyzed using a small portable device costing less than a thousand dollars. Unlike earlier intercept attempts that required analyzing many logins, the “One & Done” attack was carried out by eavesdropping on just one decryption cycle.

“This is something that could be done at an airport to steal people’s information without arousing suspicion and makes the so-called ‘coffee shop attack’ much more realistic,” said Milos Prvulovic, associate chair of Georgia Tech’s School of Computer Science. “The designers of encryption software now have another issue that they need to take into account because continuous snooping over long periods of time would no longer be required to steal this information.”

The side channel attack is believed to be the first to retrieve the secret exponent of an encryption key in a modern version of OpenSSL without relying on the cache organization and/or timing. OpenSSL is a popular encryption program used for secure interactions on websites and for signature authentication. The attack showed that a single recording of a cryptography key trace was sufficient to break 2048 bits of a private RSA key.

Results of the research, which was supported in part by the National Science Foundation, the Defense Advanced Research Projects Agency (DARPA), and the Air Force Research Laboratory (AFRL) will be presented at the 27th USENIX Security Symposium August 16th in Baltimore.

After successfully attacking the phones and an embedded system board – which all used ARM processors – the researchers proposed a fix for the vulnerability, which was adopted in versions of the software made available in May.

Side channel attacks extract sensitive information from signals created by electronic activity within computing devices during normal operation. The signals include electromagnetic emanations created by current flows within the devices computational and power-delivery circuitry, variation in power consumption, and also sound, temperature and chassis potential variation. These emanations are very different from communications signals the devices are designed to produce.

In their demonstration, Prvulovic and collaborator Alenka Zajic listened in on two different Android phones using probes located near, but not touching the devices. In a real attack, signals could be received from phones or other mobile devices by antennas located beneath tables or hidden in nearby furniture.

The “One & Done” attack analyzed signals in a relatively narrow (40 MHz wide) band around the phones’ processor clock frequencies, which are close to 1 GHz (1,000 MHz). The researchers took advantage of a uniformity in programming that had been designed to overcome earlier vulnerabilities involving variations in how the programs operate.

“Any variation is essentially leaking information about what the program is doing, but the constancy allowed us to pinpoint where we needed to look,” said Prvulovic. “Once we got the attack to work, we were able to suggest a fix for it fairly quickly. Programmers need to understand that portions of the code that are working on secret bits need to be written in a very particular way to avoid having them leak.”

The researchers are now looking at other software that may have similar vulnerabilities, and expect to develop a program that would allow automated analysis of security vulnerabilities.

“Our goal is to automate this process so it can be used on any code,” said Zajic, an associate professor in Georgia Tech’s School of Electrical and Computer Engineering. “We’d like to be able to identify portions of code that could be leaky and require a fix. Right now, finding these portions requires considerable expertise and manual examination.”

Side channel attacks are still relatively rare, but Prvulovic says the success of “One & Done” demonstrates an unexpected vulnerability. The availability of low-cost signal processing devices small enough to use in coffee shops or airports could make the attacks more practical.

“We now have relatively cheap and compact devices – smaller than a USB drive – that are capable of analyzing these signals,” said Prvulovic. “Ten years ago, the analysis of this signal would have taken days. Now it takes just seconds, and can be done anywhere – not just in a lab setting.”

Producers of mobile devices are becoming more aware of the need to protect electromagnetic signals of phones, tablets and laptops from interception by shielding their side channel emissions. Improving the software running on the devices is also important, but Prvulovic suggests that users of mobile devices must also play a security role.

“This is something that needs to be addressed at all levels,” he said. “A combination of factors – better hardware, better software and cautious computer hygiene – make you safer. You should not be paranoid about using your devices in public locations, but you should be cautious about accessing banking systems or plugging your device into unprotected USB chargers.”

In addition to those already mentioned, the research involved Monjur M. Alam, Haider A. Khan, Moutmita Dey, Nishith Sinha and Robert Callen, all of Georgia Tech.
