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 book 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.

As the use of wireless devices becomes widespread, so does the need for strong and secure transport protocols. Even with this intensified need for securing systems, using cryptography does not seem to be a viable solution due to difficulties in implementation. The security layers of many wireless protocols use outdated encryption algorithms, which have proven unsuitable for hardware usage, particularly with handheld devices. Summarizing key issues involved in achieving desirable performance in security implementations, Wireless Security and Cryptography: Specifications and Implementations focuses on alternative integration approaches for wireless communication security. It gives an overview of the current security layer of wireless protocols and presents the performance characteristics of implementations in both software and hardware. This resource also presents efficient and novel methods to execute security schemes in wireless protocols with high performance. It provides the state of the art research trends in implementations of wireless protocol security for current and future wireless communications. Unique in its coverage of specification and implementation concerns that include hardware design techniques, Wireless Security and Cryptography: Specifications and Implementations provides thorough coverage of wireless network security and recent research directions in the field.

The 16th Workshop on Selected Areas in Cryptography (SAC 2009) was held at the University of Calgary,in Calgary, Alberta, Canada, during August 13-14, 2009. There were 74 participants from 19 countries. Previous workshops in this series were held at Queens University in Kingston (1994, 1996, 1998, 1999, and 2005), Carleton University in Ottawa (1995, 1997, and 2003), University of - terloo (2000 and 2004), Fields Institute in Toronto (2001), Memorial University of Newfoundland in St. Johns (2002), Concordia University in Montreal (2006), University of Ottawa (2007), and Mount Allison University in Sackville (2008). The themes for SAC 2009 were: 1. Design and analysis of symmetric key primitives and cryptosystems, incl- ing block and stream ciphers, hash functions, and MAC algorithms 2. E?cient implementations of symmetric and public key algorithms 3. Mathematical and algorithmic aspects of applied cryptology 4. Privacy enhancing cryptographic systems This included the traditional themes (the ?rst three) together with a special theme for 2009 workshop (fourth theme).

The 11th Information Security Conference (ISC 2008) was held in Taipei, T- wan, September 15-18,2008. ISC is an annual international conference covering researchintheoryandapplicationsofinformationsecurity.Itwas?rstinitiatedas a workshop(ISW) in Japan in 1997.This was followed by ISW 1999 in Malaysia and ISW 2000 in Australia. ISW became ISC when it was held in Spain in 2001 (ISC2001).ThelatestconferenceswereheldinBrazil(ISC2002), UK(ISC2003), USA(ISC2004), Singapore(ISC2005), Greece(ISC2006), andChile(ISC2007).

In order to cover the conference's broad scope, this year's main Program Committee consisted of 61 experts from 22 countries. Additionally, the c- ference also featured a special AES Subcommittee, chaired by Vincent Rijmen (Graz University of Technology, Austria). Theconferencereceived134submissions from31countries,33(including 4 in the AES special session) of which were selected by the committee members for presentation at the conference, based on quality, originality and relevance.

This volume comprises the proceedings of the 4th Conference on Advanced - cryption Standard, 'AES - State of the Crypto Analysis, ' which was held in Bonn, Germany, during 10-12 May 2004. The conference followed a series of events organized by the US National - stitute of Standards and Technology (NIST) in order to hold an international competition to decide on an algorithm to serve as the Advanced Encryption Standard (AES). In 1998, at the ?rst AES conference (AES 1), 15 di?erent al- rithmswerepresented, discussed, reviewedandveri?ed.Asecondconferencewas organizedinApril1999, andbyAugust1999only?vecandidateswerestillinthe running: MARS, RC6, Rijndael, Serpent and Two?sh. After a further conference devoted to veri?cation, testing and examination of the candidate algorithms in order to prove their performance and security, one winning algorithm remained. The encryption scheme Rijndael, designed by the Belgian cryptographers Joan Daemen and Vincent Rijmen, was selected in 2000 to become the successor to the famous DES (Data Encryption Standard) and it is now the Advanced - cryption Standard.

This book constitutes the thoroughly refereed post-proceedings of the 9th International Workshop on Fast Software Encryption, FSE 2002, held in Leuven, Belgium in February 2002.The 21 revised full papers presented were carefully reviewed and selected from 70 submissions. The papers are organized in topical sections on blook cipher cryptoanalysis, integral cryptoanalysis, block cipher theory, stream cipher design, stream cipher cryptanalysis, and odds and ends.

The Department of Electrical Engineering-ESAT at the Katholieke Universiteit Leuven regularly runs a course on the state of the art and evolution of computer security and industrial cryptography. The rst course took place in 1983, the second in 1989, and since then the course has been a biennial event. The course is intended for both researchers and practitioners from industry and government. It covers the basic principles as well as the most recent - velopments. Our own interests mean that the course emphasizes cryptography, but we also ensure that the most important topics in computer security are covered. We try to strike a good balance between basic theory and real-life - plications, between mathematical background and judicial aspects, and between recent technical developments and standardization issues. Perhaps the greatest strength of the course is the creation of an environment that enables dialogue between people from diverse professions and backgrounds. In 1993, we published the formal proceedings of the course in the Lecture Notes in Computer Science series (Volume 741). Since the el d of cryptography has advanced considerably during the interim period, there is a clear need to publish a new edition. Since 1993, several excellent textbooks and handbooks on cryptology have been published and the need for introductory-level papers has decreased. The growth of the main conferences in cryptology (Eurocrypt, Crypto, and Asiacrypt) shows that interest in the eld is increasing
