This book constitutes the thoroughly refereed post-proceedings of the Second International Conference on Information Security and Cryptology, ICISC'99, held in Seoul, Korea, in December 1999. The 20 revised full papers presented together with an invited paper were carefully reviewed and selected from a total of 61 submissions. The book is divided into topical sections on cryptoanalysis and cryptographic design; cryptographic theory and computation complexity; cryptographic protocols and authentication design; digital signatures and secret sharing; and electronic cash, applications, and implementation.

This book constitutes the thoroughly refereed post-proceedings of the 6th International Conference on Information Security and Cryptology, ICISC 2003, held in Seoul, Korea, in November 2003. The 32 revised full papers presented together with an invited paper were carefully selected from 163 submissions during two rounds of reviewing and improvement. The papers are organized in topical sections on digital signatures, primitives, fast implementations, computer security and mobile security, voting and auction protocols, watermarking, authentication and threshold protocols, and block ciphers and stream ciphers.

This book constitutes the thoroughly refereed post-proceedings of the 5th International Conference on Information Security and Cryptology, ICISC 2002, held in Seoul, Korea in November 2002. The 35 revised full papers presented together with an invited paper were carefully selected from 142 submissions during two rounds of reviewing and improvement. The papers are organized in topical sections on digital signatures, Internet security, block ciphers and stream ciphers, stream ciphers and other primitives, efficient implementations, side-channel attacks, cryptographic protocols and biometrics.

I would like to welcome all the participants to the 3rd International Conference on Information Security and Cryptology (ICISC 2000). It is sponsored by the Korea Institute of Information Security and Cryptology (KIISC) and is being held at Dongguk University in Seoul, Korea from December 8 to 9, 2000. This conference aims at providing a forum for the presentation of new results in research, development, and application in information security and cryptology. This is also intended to be a place where research information can be exchanged. The Call for Papers brought 56 papers from 15 countries and 20 papers will be presented in ve sessions. As was the case last year the review process was totally blind and the anonymity of each submission was maintained. The 22 TPC members nally selected 20 top-quality papers for presentation at ICISC 2000. I am very grateful to the TPC members who devoted much e ort and time to reading and selecting the papers. We also thank the experts who assisted the TPC in evaluating various papers and apologize for not including their names here. Moreover, I would like to thank all the authors who submitted papers to ICISC 2000 and the authors of accepted papers for their preparation of came- ready manuscripts. Last but not least, I thank my student, Joonsuk Yu, who helped me during the whole process of preparation for the conference. I look forward to your participation and hope you will nd ICISC 2000 a truly rewarding experience.

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.

This first-of-its-kind book, from expert authors actively contributing to the evolution of Bluetooth specifications, provides an overview and detailed descriptions of all the security functions and features of this standard's latest core release. After categorizing all the security issues involved in ad hoc networking, this hands-on volume shows you how to design a highly secure Bluetooth system and implement security enhancements. The book also helps you fully understand the main security risks involved with introducing Bluetooth-based communications in your organization.

Computer Security in the 21st Century shares some of the emerging important research trends reflected in recent advances in computer security, including: security protocol design, secure peer-to-peer and ad hoc networks, multimedia security, and intrusion detection, defense and measurement. Highlights include presentations of : - Fundamental new security - Cryptographic protocols and design, - A new way of measuring network vulnerability: attack surfaces, - Network vulnerability and building impenetrable systems, - Multimedia content protection including a new standard for photographic images, JPEG2000. Researchers and computer security developers will find in this book interesting and useful insights into building computer systems that protect against computer worms, computer viruses, and other related concerns.
