This book constitutes the refereed post-conference proceedings  of the First International Conference on Number-Theoretic Methods in Cryptology,  NuTMiC 2017, held in Warsaw, Poland, in September 2017.The 15 revised full papers presented in this book together with 3 invited talks were carefully reviewed and selected from 32 initial submissions. The papers are organized in topical sections on elliptic curves in cryptography; public-key cryptography; lattices in cryptography; number theory; pseudorandomness; and algebraic structures and analysis.

This book constitutes the refereed proceedings of the 9th Australiasian Conference on Information Security and Privacy, ACISP 2004, held in Sydney, Australia in July 2004. The 41 revised full papers presented were carefully reviewed and selected from 195 submissions. The papers are organized in topical sections on broadcast encryption and traitor tracing, private information retrieval and oblivious transfer, trust and secret sharing, cryptanalysis, digital signatures, cryptosystems, fast computation, mobile agents security, protocols, security management, and access control and authorization.

This book constitutes the refereed proceedings of the Third International Workshop on Information Security, ISW 2000, held in Wollongong, Australia in December 2000. The 23 revised full papers presented were carefully reviewed and selected from 63 submissions. The papers are organized in topical sections on multimedia copyright protection, e-commerce, key management, network security and access control, and cryptographic systems.

This reference work looks at modern concepts of computer security. It introduces the basic mathematical background necessary to follow computer security concepts before moving on to modern developments in cryptography. The concepts are presented clearly and illustrated by numerous examples. Subjects covered include: private-key and public-key encryption, hashing, digital signatures, authentication, secret sharing, group-oriented cryptography, and many others. The section on intrusion detection and access control provide examples of security systems implemented as a part of operating system. Database and network security is also discussed. The final chapters introduce modern e- business systems based on digital cash.

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 algorithm design. 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 without secrecy. Covering all practical and theoretical issues related to the design of secure hashing algorithms the book is self contained; it includes an extensive bibliography on the 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.
