About this product: If you're looking to fully understand and effectively implement identity-based encryption (IBE) technology, this authoritative resource is a smart choice. Until now, details on IBE have only been found in cumbersome, hard-to-follow journal articles and conference proceedings. This is the first book to offer you complete, easy-to-understand guidance on the subject. Comparing and contrasting IBE with traditional public-key technologies, the book clearly explains how and why IBE systems are secure. You find a wealth of practical techniques, algorithms and numerous worked examples that enable you to create a secure IBE system.
From basic mathematical concepts and properties, properties of elliptic curves, divisors and the Tate pairing, and cryptography and computational complexity, to related cryptographic algorithms, various IBE schemes, hierarchical IBE and master secret planning, and calculating pairings, this comprehensive volume serves as a clear guide to this increasingly important security technology. This hands-on volume includes detailed pseudocode for identity-based encryption algorithms and supporting algorithms that help save you time and simplify your challenging projects in the field.
In the 1960s, it became increasingly clear that more and more information was going to be stored on computers, not on pieces of paper. With these changes in technology and the ways it was used came a need to protect both the systems and the information. For the next ten years, encryption systems of varying strengths were developed, but none proved to be rigorous enough. In 1973, the NBS put out an open call for a new, stronger encryption system that would become the new federal standard. Several years later, IBM responded with a system called Lucifer that came to simply be known as DES (data encryption standard).
The strength of an encryption system is best measured by the attacks it is able to withstand, and because DES was the federal standard, many tried to test its limits. (It should also be noted that a number of cryptographers and computer scientists told the NSA that DES was not nearly strong enough and would be easily hacked.) Rogue hackers, usually out to steal as much information as possible, tried to break DES. A number of "white hat" hackers also tested the system and reported on their successes. Still others attacked DES because they believed it had outlived its effectiveness and was becoming increasingly vulnerable. The sum total of these efforts to use all of the possible keys to break DES over time made for a brute force attack.
In 1996, the supposedly uncrackable DES was broken. In this captivating and intriguing book, Matt Curtin charts DES’s rise and fall and chronicles the efforts of those who were determined to master it.
About this product: Protect Your Enterprise Data with Rock-Solid Database Encryption If hackers compromise your critical information, the results can be catastrophic. You're under unprecedented pressure--from your customers, your partners, your stockholders, and now, the government--to keep your data secure. But what if hackers evade your sophisticated security mechanisms? When all else fails, you have one last powerful line of defense: database cryptography. In this book, a leading crypto expert at Symantec demonstrates exactly how to use encryption with your own enterprise databases and applications. Kevin Kenan presents a start-to-finish blueprint and execution plan for designing and building--or selecting and integrating--a complete database cryptosystem. Kenan systematically shows how to eliminate weaknesses, overcome pitfalls, and defend against attacks that can compromise data even if it's been protected by strong encryption. This book's 3,000 lines of downloadable code examples let you explore every component of a live database cryptosystem, including key vaults and managers, manifests, engines, and providers.This book's coverage includes * Understanding your legal obligations to protect data * Constructing a realistic database security threat model and ensuring that you address critical threats * Designing robust database cryptographic infrastructure around today's most effective security patterns * Hardening your database security requirements * Classifying the sensitivity of your data * Writing database applications that interact securely with your cryptosystem * Avoiding the common vulnerabilities that compromise database applications * Managing cryptographic projects in your enterprise database environment * Testing, deploying, defending, and decommissioning secure database applications Cryptography in the Database is an indispensable resource for every professional who must protect enterprise data: database architects, administrators, and developers; system and security analysts; and many others.

The Belgian block cipher Rijndael was chosen in 2000 by the U.S. government’s National Institute of Standards and Technology (NIST) to be the successor to the Data Encryption Standard. Rijndael was subsequently standardized as the Advanced Encryption Standard (AES), which is potentially the world’s most important block cipher. In 2002, some new analytical techniques were suggested that may have a dramatic effect on the security of the AES. Existing analytical techniques for block ciphers depend heavily on a statistical approach, whereas these new techniques are algebraic in nature.
Algebraic Aspects of the Advanced Encryption Standard, appearing five years after publication of the AES, presents the state of the art for the use of such algebraic techniques in analyzing the AES.
The primary audience for this work includes academic and industry researchers in cryptology; the book is also suitable for advanced-level students.
About this product: In October 2000, the US National Institute of Standards and Technology selected the block cipher Rijndael as the Advanced Encryption Standard (AES). AES is expected to gradually replace the present Data Encryption Standard (DES) as the most widely applied data encryption technology.|This book by the designers of the block cipher presents Rijndael from scratch. The underlying mathematics and the wide trail strategy as the basic design idea are explained in detail and the basics of differential and linear cryptanalysis are reworked. Subsequent chapters review all known attacks against the Rijndael structure and deal with implementation and optimization issues. Finally, other ciphers related to Rijndael are presented.|This volume is THE authoritative guide to the Rijndael algorithm and AES. Professionals, researchers, and students active or interested in data encryption will find it a valuable source of information and reference.
About this product: In Cryptography and Liberty 2000, the Electronic Privacy Information Center (EPIC)'s third survey of encryption policy around the globe, EPIC finds that the effort to reduce export regulations that limit the availability of encryption has largely succeeded. The rise of electronic commerce and the need to protect privacy and increase the security of the Internet have resulted in the development of policies that favor the spread of strong encryption worldwide. However, while the impact of export controls on the use and production of encryption continues to diminish, new domestic regulations and new powers for law enforcement authorities raise ongoing questions about the freedom to use encryption and other privacy enhancing techniques.
