Network Security

This volume highlights and addresses several key challenges in the area of Network Security. Covered is a comprehensive array of topics including secure metering, group key management, denial-of-service attacks, routing and intrusion detection and many more. The book contains eleven peer reviewed chapters, authored by prominent researchers from around the globe. Although the topics do not cover every aspect of network security, they do represent the most fundamental and practical techniques. Network Security should be of interest to researchers and network security experts in the field.

Sometimes you have to do good engineering to straighten out twisted politics. The Electronic Frontier Foundation, a nonprofit organization that was founded to ensure that the principles embodied in the Constitution and Bill of Rights are protected as new communications technologies emerge, and O"Reilly, the premier publisher of computer and computer-related books, team up to produce Cracking DES: Secrets of Encryption Research, Wiretap Politics & Chip Design. By doing this they have exploded the government-supported myth that the Data Encryption Standard (DES) has real security.

National Security Agency and FBI officials say our civil liberties must be curtailed because the government can't crack the security of DES to wiretap bad guys. But somehow a tiny nonprofit has designed and built a $200,000 machine that cracks DES in a week. Who's lying, and why?

For the first time, the book reveals full technical details on how researchers and data-recovery engineers can build a working DES Cracker. It includes design specifications and board schematics, as well as full source code for the custom chip, a chip simulator, and the software that drives the system. The U.S. government makes it illegal to publish these details on the Web, but they're printed here in a form that's easy to read and understand, legal to publish, and convenient for scanning into your computer.

The Data Encryption Standard withstood the test of time for twenty years. This book shows exactly how it was brought down. Every cryptographer, security designer, and student of cryptography policy should read this book to understand how the world changed as it fell.

Over the past two decades, network technologies have been remarkably renovated and computer networks, particularly the Internet, have permeated into every facet of our daily lives. These changes also brought about new challenges, particularly in the area of security. Network security is essential to protect data integrity, con?d- tiality, access control, authentication, user privacy, and so on. All of these aspects are critical to provide fundamental network functionalities. This book covers a comprehensive array of topics in network security including secure metering, group key management, DDoS attacks, and many others. It can be used as a handy reference book for researchers, educators, graduate students, as well as professionals in the ?eld of network security. This book contains 11 r- ereed chapters from prominent researchers working in this area around the globe. Although these selected topics could not cover every aspect, they do represent the most fundamental and practical techniques. This book has been made possible by the great efforts and contributions of many people. First, we thank the authors of each chapter for contributing informative and insightful chapters. Then, we thank all reviewers for their invaluable comments and suggestions that improved the quality of this book. Finally, we thank the staff m- bers from Springer for publishing this work. Besides, we would like to dedicate this book to our families. Rijndael was the surprise winner of the contest for the new Advanced En­ cryption Standard (AES) for the United States. This contest was organized and run by the National Institute for Standards and Technology (NIST) be­ ginning in January 1997; Rijndael was announced as the winner in October 2000. It was the'surprise winner'because many observers (and even some participants) expressed scepticism that the D.S. government would adopt as an encryption standard any algorithm that was not designed by D.S. citizens. Yet NIST ran an open, international, selection process that should serve as model for other standards organizations. For example, NIST held their 1999 AES meeting in Rome, Italy. The five finalist algorithms were designed by teams from all over the world. In the end, the elegance, efficiency, security, and principled design of Rijndael won the day for its two Belgian designers, Joan Daemen and Vincent Rijmen, over the competing finalist designs from RSA, IBM, Counterpane Systems, and an EnglishjIsraelijDanish team. This book is the story of the design of Rijndael, as told by the designers themselves. It outlines the foundations of Rijndael in relation to the previous ciphers the authors have designed. It explains the mathematics needed to and the operation of Rijndael, and it provides reference C code and underst test vectors for the cipher.

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.

Coverage includes network design and modeling, network management, data management, security and applications. The Data Encryption Standard withstood the test of time for 20 years. This text shows exactly how it was brought down. It should be of interest to cryptographers, security designers, and students of cryptography policy. In January 1997, the US National Institute of Standards and Technology (NIST) announced the start of an initiative to develop a new encryption standard: the AES.
