These are the proceedings of Eurocrypt 2008, the 27th Annual IACR Eu- crypt Conference. The conference was sponsored by the International Asso- ation for Cryptologic Research (www.iacr.org), this year in cooperation with Tubitak (www.tubitak.gov.tr). The Eurocrypt 2008 Program Committee (PC) consisted of 28 members whose names are listed on the next page. There were 163 papers submitted to the conference and the PC chose 31 of them. Each paper was assigned to at least three PC members, who either handled it themselves or assigned it to an external referee. After the reviews were submitted, the committee deliberated both online for severalweeks and?nally ina face-to-facemeetingheldinBristol. Papers were refereed anonymously, with PC papers having a minimum of ?ve reviewers. All of our deliberations were aided by theWeb Submission and- viewSoftware written and maintainedby Shai Halevi. In addition to noti?cation of the decision of the committee, authors received reviews; the default for any report given to the committee was that it should be available to the authors as well.

Here is a highly relevant book that covers a wide array of key aspects in information security. It constitutes the refereed proceedings of the 12th Australasian Conference on Information Security and Privacy held in Townsville, Australia in July 2007. The 33 revised full papers presented were carefully reviewed and selected from 132 submissions. The papers are organized in topical sections on stream ciphers, hashing, biometrics, secret sharing, cryptanalysis, public key cryptography, authentication, e-commerce, and security.

So much of what is commonplace today was once considered impossible, or at least wishful thinking. Laser beams in the operating room, cars with built-in guidance systems, cell phones with email access. There's just no getting around the fact that technology always has, and always will be, very cool.

But technology isn't only cool; it's also very smart. That's why one of the hottest technological trends nowadays is the creation of smart homes.

At an increasing rate, people are turning their homes into state-of-the-art machines, complete with more switches, sensors, and actuators than you can shake a stick at. Whether you want to equip your home with motion detectors for added security, install computer-controlled lights for optimum convenience, or even mount an in-home web cam or two purely for entertainment, the world is now your oyster. Ah, but like anything highly technical, creating a smart home is typically easier said than done.

Thankfully, "Smart Home Hacks" takes the guesswork out of the process. Through a seemingly unending array of valuable tips, tools, and techniques, "Smart Home Hacks" explains in clear detail how to use Mac, Windows, or Linux to achieve the automated home of your dreams. In no time, you'll learn how to turn a loose collection of sensors and switches into a well-automated and well-functioning home no matter what your technical level may be.

"Smart Home Hacks" covers a litany of stand-alone and integrated smart home solutions designed to enhance safety, comfort, and convenience in new and existing homes. Kitchens, bedrooms, home offices, living rooms, and even bathrooms are all candidates for smart automation and therefore are all addressed in"Smart Home Hacks,"

Intelligently written by engineering guru and George Jetson wannabe, Gordon Meyer, "Smart Home Hacks" leaves no stone unturned. From what to purchase to how to use your remote control, it's the ultimate guide to understanding and implementing complete or partial home automation.

This book constitutes the refereed proceedings of the Pacific Asia Workshop on Intelligence and Security Informatics, PAISI 2007, held in Chengdu, China in April 2007.

Cryptography is a vital technology that underpins the security of information in computer networks. This book presents a comprehensive introduction to the role that cryptography plays in providing information security for everyday technologies such as the Internet, mobile phones, Wi-Fi networks, payment cards, Tor, and Bitcoin. This book is intended to be introductory, self-contained, and widely accessible. It is suitable as a first read on cryptography. Almost no prior knowledge of mathematics is required since the book deliberately avoids the details of the mathematics techniques underpinning cryptographic mechanisms. Instead our focus will be on what a normal user or practitioner of information security needs to know about cryptography in order to understand the design and use of everyday cryptographic applications. By focusing on the fundamental principles of modern cryptography rather than the technical details of current cryptographic technology, the main part this book is relatively timeless, and illustrates the application of these principles by considering a number of contemporary applications of cryptography. Following the revelations of former NSA contractor Edward Snowden, the book considers the wider societal impact of use of cryptography and strategies for addressing this. A reader of this book will not only be able to understand the everyday use of cryptography, but also be able to interpret future developments in this fascinating and crucially important area of technology.

The common use of the Internet and cloud services in transmission of large amounts of data over open networks and insecure channels, exposes that private and secret data to serious situations. Ensuring the information transmission over the Internet is safe and secure has become crucial, consequently information security has become one of the most important issues of human communities because of increased data transmission over social networks. Digital Media Steganography: Principles, Algorithms, and Advances covers fundamental theories and algorithms for practical design, while providing a comprehensive overview of the most advanced methodologies and modern techniques in the field of steganography. The topics covered present a collection of high-quality research works written in a simple manner by world-renowned leaders in the field dealing with specific research problems. It presents the state-of-the-art as well as the most recent trends in digital media steganography.

This succinct book departs from other security literature by focusing exclusively on ways to secure Cisco routers, rather than the entire network. The rational is simple: If the router protecting a network is exposed to hackers, then so is the network behind it. This is a reference for protecting the protectors, and author Thomas Akin supplies all the tools necessary to turn a potential vulnerability into a strength.

Electronic commerce is changing the way that businesses and consumers interact with each other; the products they create, buy, and sell; and the way that they communicate, learn, and become informed. How can policymakers position their countries and themselves to take advantage of this new environment? How should policymaking adjust to a more global, more networked, and more information-rich marketplace where relationships and jurisdictions between the governments, businesses, and citizens of different countries increasingly overlap? How can governments effectively harness rapidly changing technologies and partner with both domestic and foreign private sectors to reap the greatest benefits for their constituents?

This primer answers these questions using both general analysis and specific examples. It addresses in particular the needs of policymakers in emerging markets who must formulate and refine policies that affect e-commerce in areas ranging from telecommunications and finance to international trade and domestic distribution as well as taxation and privacy. Companies considering doing business in these economies also will find that the examples offer insights into the issues that policymakers face, the different policy approaches that they choose, and the market opportunities that result as more and more economies embrace global electronic commerce.

Today, more than 80% of the data transmitted over networks and archived on our computers, tablets, cell phones or clouds is multimedia data - images, videos, audio, 3D data. The applications of this data range from video games to healthcare, and include computer-aided design, video surveillance and biometrics. It is becoming increasingly urgent to secure this data, not only during transmission and archiving, but also during its retrieval and use. Indeed, in today's "all-digital" world, it is becoming ever-easier to copy data, view it unrightfully, steal it or falsify it. Multimedia Security 1 analyzes the issues of the authentication of multimedia data, code and the embedding of hidden data, both from the point of view of defense and attack. Regarding the embedding of hidden data, it also covers invisibility, color, tracing and 3D data, as well as the detection of hidden messages in an image by steganalysis.

If you are a network administrator, you're under a lot of pressure to ensure that mission-critical systems are completely safe from malicious code, buffer overflows, stealth port scans, SMB probes, OS fingerprinting attempts, CGI attacks, and other network intruders. Designing a reliable way to detect intruders before they get in is an essential--but often overwhelming--challenge. Snort, the defacto open source standard of intrusion detection tools, is capable of performing real-time traffic analysis and packet logging on IP network. It can perform protocol analysis, content searching, and matching. Snort can save countless headaches; the new "Snort Cookbook" will save countless hours of sifting through dubious online advice or wordy tutorials in order to leverage the full power of SNORT.

Each recipe in the popular and practical problem-solution-discussion O'Reilly cookbook format contains a clear and thorough description of the problem, a concise but complete discussion of a solution, and real-world examples that illustrate that solution. The "Snort Cookbook" covers important issues that sys admins and security pros will us everyday, such as:

Cyber Crime and Cyber Terrorism Investigator's Handbook describes and analyzes many of the motivations, tools, and tactics behind cyber attacks and the defenses against them. With this book, you will learn about the technological and logistic framework of cyber crime, as well as the social and legal backgrounds of its prosecution and investigation. Whether you are a law enforcement professional, an IT specialist, a researcher, or a student, you will find valuable insight into the world of cyber crime and cyber warfare. Edited by experts in computer security, cyber investigations, and counter-terrorism, and with contributions from computer researchers, legal experts, and law enforcement professionals, Cyber Crime and Cyber Terrorism Investigator's Handbook will serve as your best reference to the modern world of cyber crime.

With the spread of web-enabled desktop clients and web-server based applications, developers can no longer afford to treat security as an afterthought. It's one topic, in fact, that .NET forces you to address, since Microsoft has placed security-related features at the core of the .NET Framework. Yet, because a developer's carelessness or lack of experience can still allow a program to be used in an unintended way, Programming .NET Security shows you how the various tools will help you write secure applications.
