This book constitutes the thoroughly refereed postproceedings of the 7th International Conference on Information Security and Cryptology, ICISC 2004, held in Seoul, Korea in December 2004. The 34 revised full papers presented have gone through two rounds of reviewing and improvement and were selected from 194 submissions. The papers are organized in topical sections on block ciphers and stream ciphers, public key cryptosystems, PKI and related implementations, digital signatures, elliptic curve cryptosystems, provable security and primitives, network security, steganography, and biometrics.

The 8th International Conference on Information Security and Cryptology was organized by the Korea Institute of Information Security and Cryptology (KIISC) and sponsored by the Ministry of Information and Communication of Korea (MIC).

The ?rst SKLOIS Conference on Information Security and Cryptography(CISC 2005) was organized by the State Key Laboratory of Information Security of the Chinese Academy of Sciences. It was held in Beijing, China, December 15-17,2005andwassponsoredbytheInstituteofSoftware,theChineseAcademy of Sciences, the Graduate School of the Chinese Academy of Sciences and the National Science Foundation of China. The conference proceedings, represe- ing invited and contributed papers, are published in this volume of Springer’s Lecture Notes in Computer Science (LNCS) series. The area of research covered by CISC has been gaining importance in recent years, and a lot of fundamental, experimental and applied work has been done, advancing the state of the art. The program of CISC 2005 covered numerous ?elds of research within the general scope of the conference. The International Program Committee of the conference received a total of 196 submissions (from 21 countries). Thirty-three submissions were selected for presentation as regular papers and are part of this volume. In addition to this track, the conference also hosted a short-paper track of 32 presentations that were carefully selected as well. All submissions were reviewed by experts in the relevant areas and based on their ranking and strict selection criteria the papers were selected for the various tracks. We note that stricter criteria were applied to papers co-authored by program committee members. We further note that, obviously, no member took part in in?uencing the ranking of his or her own submissions.

The 3rd International Conference on Applied Cryptography and Network Security (ACNS 2005) was sponsored and organized by ICISA (the International Commu- cations and Information Security Association). It was held at Columbia University in New York, USA, June 7–10, 2005. This conference proceedings volume contains papers presented in the academic/research track. ACNS covers a large number of research areas that have been gaining importance in recent years due to the development of the Internet, wireless communication and the increased global exposure of computing resources. The papers in this volume are representative of the state of the art in security and cryptography research, worldwide. The Program Committee of the conference received a total of 158 submissions from all over the world, of which 35 submissions were selected for presentation at the a- demic track. In addition to this track, the conference also hosted a technical/ industrial/ short papers track whose presentations were also carefully selected from among the submissions. All submissions were reviewed by experts in the relevant areas.

This book constitutes the refereed proceedings of the 9th International Conference on Information Security and Cryptology, ICISC 2006, held in Busan, Korea in November/December 2006. The 26 revised full papers cover such topics as hash functions, block and stream ciphers, network security and access control, mobile communications security, forensics, copyright protection, biometrics, public key cryptosystems, and digital signatures.

This book constitutes the thoroughly refereed post-proceedings of the Second European Workshop on Security and Privacy in Ad hoc and Sensor Networks, ESAS 2005, held in Visegrad, Hungary in July 2005, in conjunction with the First International Conference on Wireless Internet (WICON). The 17 revised full papers were carefully reviewed and selected from a total of 51 submissions. The papers address current topics in network security, cryptography, and wireless networking communities and present original research on all aspects of security and privacy in wireless ad hoc and sensor networks.

During recent years, a continuously increasing amount of personal data has been made available through different websites around the world. Although the availability of personal information has created several advantages, it can be easily misused and may lead to violations of privacy. With growing interest in this area, Digital Privacy: Theory, Technologies, and Practices addresses this timely issue, providing information on state-of-the-art technologies, best practices, and research results, as well as legal, regulatory, and ethical issues. This book features contributions from experts in academia, industry, and government.

This book constitutes the refereed proceedings of the 6th International Workshop on Information Security Applications, WISA 2005, held in Jeju Island, Korea, in August 2005. The 29 revised full papers presented were carefully selected during two rounds of reviewing and improvement from 168 submissions. The papers are organized in topical sections on security analysis and attacks, systems security, network security, DRM/software security, efficient HW implementation, side-channel attacks, privacy/anonymity, and efficient implementation.

This book contains the proceedings of the 2nd EuroPKI Workshop — EuroPKI 2005, held at the University of Kent in the city of Canterbury, UK, 30 June–1 July 2005. The workshop was informal and lively, and the university setting encouragedactive exchangesbetween the speakersand the audience. TheworkshopprogramcomprisedakeynotespeechfromDr.CarlisleAdams, followedby18refereedpapers,withaworkshopdinnerinandguidedtouraround the historic Dover Castle. Dr. Adams is well known for his contributions to the CAST family of s- metric encryption algorithms, to international standards from the IETF, ISO, and OASIS, authorship of over 30 refereed journals and conference papers, and co-authorship of Understanding PKI: Concepts, Standards, and Deployment Considerations (Addison-Wesley). Dr. Adams keynote speech was entitled ‘PKI: Views from the Dispassionate “I”,’ in which he presented his thoughts on why PKIhas been availableas an authentication technology for many years now,but has only enjoyed large-scale success in fairly limited contexts to date. He also presented his thoughts on the possible future(s) of this technology, with emp- sis on the major factors hindering adoption and some potential directions for future research in these areas. In response to the Call for Papers, 43 workshop papers were submitted in total. All papers were blind reviewed by at least two members of the Program Committee, the majority having 3 reviewers, with a few borderline papers h- ing 4 or more reviewers; 18 papers were accepted for presentation in 8 sessions.
