This book constitutes the refereed post-conference proceedings of the 4th International Conference on Number-Theoretic Methods in Cryptology, NuTMiC 2024, held in Szczecin, Poland, during June 24–26, 2024.The 9 full papers and 2 invited papers presented in this book were carefully reviewed and selected from 12 submissions. They were organized in topical sections as follows: invited talks; elliptic curves in cryptography; number theory; algebraic structures and public-key cryptography.

The two volume set LNCS 10342 and 10343 constitutes the refereed Proceedings of the 22nd Australasian Conference on Information Security and Privacy, ACISP 2017, held in Auckland, New Zealand, in July 2017. The 45 revised full papers,  2 keynotes, 8 invited papers and 10 short papers  presented in this double volume, were carefully revised and selected from  150 submissions. The papers of Part I (LNCS 10342) are organized in topical  sections on public key encryption; attribute-based encryption; identity-based encryption; searchable encryption; cryptanalysis; digital signatures. The papers  of Part II (LNCS 10343) are organized in topical sections on symmetric cryptography; software security; network security; malware detection; privacy; authentication; elliptic curve cryptography.

The 9th Australasian Conference on Information Security and Privacy (ACISP 2004) was held in Sydney, 13–15 July, 2004. The conference was sponsored by the Centre for Advanced Computing – Algorithms and Cryptography (ACAC), Information and Networked Security Systems Research (INSS), Macquarie U- versity and the Australian Computer Society. Theaimsoftheconferencearetobringtogetherresearchersandpractitioners working in areas of information security and privacy from universities, industry and government sectors. The conference program covered a range of aspects including cryptography, cryptanalysis, systems and network security. The program committee accepted 41 papers from 195 submissions. The - viewing process took six weeks and each paper was carefully evaluated by at least three members of the program committee. We appreciate the hard work of the members of the program committee and external referees who gave many hours of their valuable time. Of the accepted papers, there were nine from Korea, six from Australia, ?ve each from Japan and the USA, three each from China and Singapore, two each from Canada and Switzerland, and one each from Belgium, France, Germany, Taiwan, The Netherlands and the UK. All the authors, whether or not their papers were accepted, made valued contributions to the conference. In addition to the contributed papers, Dr Arjen Lenstra gave an invited talk, entitled Likely and Unlikely Progress in Factoring. ThisyeartheprogramcommitteeintroducedtheBestStudentPaperAward. The winner of the prize for the Best Student Paper was Yan-Cheng Chang from Harvard University for his paper Single Database Private Information Retrieval with Logarithmic Communication.

The third International Workshop on Information Security was held at the U- versity of Wollongong, Australia. The conference was sponsored by the Centre for Computer Security Research, University of Wollongong. The main themes of the conference were the newly emerging issues of Information Security. Mul- media copyright protection and security aspects of e-commerce were two topics that clearly re?ect the focus of the conference. Protection of the copyright of electronic documents seems to be driven by strong practical demand from the industry for new, e cient and secure solutions. Although e-commerce is already booming, it has not reached its full potential in terms of new, e cient and secure e-commerce protocols with added properties. There were 63 papers submitted to the conference. The program committee accepted 23. Of those accepted, six papers were from Australia, ve from Japan, two each from Spain, Germany and the USA, and one each from Finland and Sweden. Four papers were co-authored by international teams from Canada and China, Korea and Australia, Taiwan and Australia, and Belgium, France and Germany, respectively. Final versions of the accepted papers were gathered using computing and other resources of the Institute of Mathematics, Polish Academy of Sciences, Warsaw, Poland. We are especially grateful to Jerzy Urbanowicz and Andrzej Pokrzywa for their help during preparation of the proceedings.

The book studies modern concepts of Computer Security. It is selfcontained in the sense that it introduces the basic mathematical background necessary to follow computer security concepts.

This volume is a collection of refereed papers presented during AUSCRYPT '90 held in Sydney, Australia, January 8-11, 1990. This was the first conference of a series sponsored by the International Association for Cryptological Research (IACR) in addition to the EUROCRYPT series held in European countries and the CRYPTO series held in Santa Barbara, California. The volume is divided into sections on: - Public-key cryptosystems - Pseudorandomness and sequences - Network security - Authentication - Block ciphers - Zero-knowledge protocols - Theory - Applications - Implementations. It is a "must" for all researchers and students interested in recent progress in cryptology.

This work presents recent developments in hashing algorithmdesign. Hashing is the process of creating a short digest(i.e., 64 bits) for a message of arbitrary length, for exam-ple 20 Mbytes. Hashing algorithms were first used for sear-ching records in databases; they are central for digital si-gnature applications and are used for authentication withoutsecrecy. Covering all practical and theoretical issuesrelated to the design of secure hashing algorithms the bookis self contained; it includes an extensive bibliography onthe topic.

This book constitutes the thoroughly refereed post-conference proceedings of the First Australiasian Conference on Information Security and Privacy, ACISP '96, held in Wollongong, NSW, Australia, in June 1996.The volume includes revised full versions of the 26 refereed papers accepted for presentation at the conference; also included are three invited contributions. The papers are organized in topical sections on authentication, secret sharing, encryption and cryptographic functions, authentication protocols, stream ciphers, access control, security models and intrusion detection, threshold cryptography, and hashing.

This book constitutes the refereed proceedings of the Second Australasian Conference on Information Security and Privacy, ACISP'97, held in Sydney, NSW, Australia, in July 1997.The 20 revised full papers presented were carefully selected for inclusion in the proceedings. The book is divided into sections on security models and access control, network security, secure hardware and implementation issues, cryptographic functions and ciphers, authentication codes and secret sharing systems, cryptanalysis, key escrow, security protocols and key management, and applications.

The RSA Conference is an annual event that attracts hundreds of vendors and thousands of participants from industry and academia. Since 2001, the conf- ence has included an academic Cryptographers'Track (CT-RSA). This year was the 10th anniversary of CT-RSA. Since its conception, the CT-RSA conference has become a major avenue for publishing high-quality research papers. The RSA conference was held in San Francisco, California, during March 1-5, 2010. This year we received94 submissions. Eachpaper gotassignedto three ref- ees. Papers submitted by the members of the Program Committee got assigned to?vereferees.Inthe?rststageofthereviewprocess,thesubmittedpaperswere read and evaluated by the ProgramCommittee members and then in the second stage, the papers were scrutinized during an extensive discussion. Finally, the Program Committee chose 25 papers to be included in the conference program. The authors of the accepted papers had two weeks for revision and preparation of ?nal versions.The revised papers were not subject to editorial review and the authors bear full responsibility for their contents.The submission and review process was supported by the iChair conference submission server. We thank Matthiew Finiasz and Thomas Baign' eres for letting us use iChair. The conf- ence proceedings were published by Springer in this volume of Lecture Notes in Computer Science.
