This volume constitutes the refereed proceedings of the 7th International Conference on Smart Card Research and Advanced Applications, CARDIS 2006, held in Tarragona, Spain, in April 2006. The 25 revised full papers presented were carefully reviewed and updated for inclusion in this book. The papers are organized in topical sections on smart card applications, side channel attacks, smart card networking, cryptographic protocols, RFID security, and formal methods.

This book constitutes the thoroughly refereed post-conference proceedings of the 18th International Conference on Smart Card Research and Advanced Applications, CARDIS 2019, held in Prague, Czech Republic, in November 2019. The 15 revised full papers presented in this book were carefully reviewed and selected from 31 submissions. The papers are organized in the following topical sections: system-on-a-chip security; post-quantum cryptography; side-channel analysis; microarchitectural attacks; cryptographic primitives; advances in side-channel analysis. CARDIS has provided a space for security experts from industry and academia to exchange on security of smart cards and related applications.

The12thintheseriesofIMAConferencesonCryptographyandCodingwasheld at the Royal Agricultural College, Cirencester, December 15–17, 2009. The p- gram comprised 3 invited talks and 26 contributed talks. The contributed talks werechosenbyathoroughreviewingprocessfrom53submissions.Oftheinvited and contributed talks,28 arerepresentedaspapersin this volume. These papers are grouped loosely under the headings: Coding Theory, Symmetric Crypt- raphy, Security Protocols, Asymmetric Cryptography, Boolean Functions, and Side Channels and Implementations. Numerous people helped to make this conference a success. To begin with I would like to thank all members of the Technical Program Committee who put a great deal of e?ort into the reviewing process so as to ensure a hi- quality program. Moreover, I wish to thank a number of people, external to the committee, who also contributed reviews on the submitted papers. Thanks, of course,mustalso goto allauthorswho submitted papers to the conference,both those rejected and accepted. The review process was also greatly facilitated by the use of the Web-submission-and-review software, written by Shai Halevi of IBM Research, and I would like to thank him for making this package available to the community. The invited talks were given by Frank Kschischang, Ronald Cramer, and Alexander Pott, and two of these invitedtalksappearaspapersinthisvolume. A particular thanks goes to these invited speakers, each of whom is well-known, notonlyforbeingaworld-leaderintheir?eld,butalsofortheirparticularability to communicate their expertise in an enjoyable and stimulating manner.

The five-volume set, LNCS 14081, 140825, 14083, 14084, and 14085 constitutes the refereed proceedings of the 43rd Annual International Cryptology Conference, CRYPTO 2023. The conference took place at Santa Barbara, USA, during August 19-24, 2023. The 124 full papers presented in the proceedings were carefully reviewed and selected from a total of 479 submissions. The papers are organized in the following topical sections: Part I: Consensus, secret sharing, and multi-party computation; Part II: Succinctness; anonymous credentials; new paradigms and foundations; Part III: Cryptanalysis; side channels; symmetric constructions; isogenies; Part IV: Faster fully homomorphic encryption; oblivious RAM; obfuscation; secure messaging; functional encryption; correlated pseudorandomness; proof systems in the discrete-logarithm setting.

It is an honor and great pleasure to write a preface for this postproceedings of the 6th International Workshop on Information Hiding. In the past 10 years, the field of data hiding has been maturing and expanding, gradually establishing its place as an active interdisciplinary research area uniquely combining information theory, cryptology, and signal processing. This year, the workshop was followed by the Privacy Enhancing Technologies workshop (PET) hosted at the same location. Delegates viewed this connection as fruitful as it gave both communities a convenient opportunity to interact. We would like to thank all authors who submitted their work for consideration. Out of the 70 submisions received by the program committee, 25 papers were accepted for publication based on their novelty, originality, and scientific merit. We strived to achieve a balanced exposition of papers that would represent many different aspects of information hiding. All papers were divided into eight sessions: digital media watermarking, steganalysis, digital forensics, steganography, software watermarking, security and privacy, anonymity, and data hiding in unusual content. This year, the workshop included a one-hour rump session that offered an opportunity to the delegates to share their work in progress and other brief but interesting contributions.

This book constitutes the refereed proceedings of the 8th International Conference on Information and Communications Security, ICICS 2006, held in Raleigh, NC, USA, December 2006. The 22 revised full papers and 17 revised short papers cover security protocols, applied cryptography, access control, privacy and malicious code, network security, systems security, cryptanalysis, applied cryptography and network security, and security implementations.
