This book constitutes the post-conference proceedings of the 15th International Conference on Information Security and Cryptology, Inscrypt 2019, held in Nanjing, China, in December 2019. The 23 full papers presented together with 8 short papers and 2 invited papers were carefully reviewed and selected from 94 submissions. The papers cover topics in the fields of post-quantum cryptology; AI security; systems security; side channel attacks; identity-based cryptography; signatures; cryptanalysis; authentication; and mathematical foundations.

The 8th International Conference on Cryptology and Network Security (CANS 2009) was held at the Ishikawa Prefectural Museum of Art in Kanazawa,Japan, during December 12–14, 2009. The conference was jointly co-organized by the NationalInstituteofAdvancedIndustrialScienceandTechnology(AIST),Japan, and the Japan Advanced Institute of Science and Technology (JAIST). In ad- tion, the event was supported by the Special Interest Group on Computer Se- rity (CSEC), IPSJ, Japan, the Japan Technical Group on Information Security (ISEC), IEICE, the Japan Technical Committee on Information and Com- nication System Security(ICSS), IEICE, and the Society of Information Theory and its Applications (SITA), Japan, and co-sponsored by the National Ins- tute of Information and Communications Technology, Japan, ComWorth Co. , LTD, Japan, Hitachi, Ltd. , Hokuriku Telecommunication Network Co. ,Inc. , and Internet Initiative Japan Inc. The conference received 109 submissions from 24 countries, out of which 32 were accepted for publication in these proceedings. At least three Program Committee (PC) members reviewed each submitted paper, while submissions co-authored by a PC member were submitted to the more stringent evaluation of ?ve PC members. In addition to the PC members, many external reviewers joinedthereviewprocessintheirparticularareasofexpertise. Wewerefortunate to have this energetic team of experts, and are deeply grateful to all of them for their hard work, which included a very active discussion phase—almost as long as the initial individual reviewing period. The paper submission, review and discussion processes were e?ectively and e?ciently made possible by the Web-based system iChair.

Information security is everyone's concern. The way we live is underwritten by information system infrastructures, most notably the Internet. The functioning of our business organizations, the management of our supply chains, and the operation of our governments depend on the secure flow of information. In an organizational environment information security is a never-ending process of protecting information and the systems that produce it.This volume in the "Advances in Management Information Systems" series covers the managerial landscape of information security. It deals with how organizations and nations organize their information security policies and efforts. The book covers how to strategize and implement security with a special focus on emerging technologies. It highlights the wealth of security technologies, and also indicates that the problem is not a lack of technology but rather its intelligent application.

Recent advancements and innovations in medical image and data processing have led to a need for robust and secure mechanisms to transfer images and signals over the internet and maintain copyright protection. The Handbook of Research on Information Security in Biomedical Signal Processing provides emerging research on security in biomedical data as well as techniques for accurate reading and further processing. While highlighting topics such as image processing, secure access, and watermarking, this publication explores advanced models and algorithms in information security in the modern healthcare system. This publication is a vital resource for academicians, medical professionals, technology developers, researchers, students, and practitioners seeking current research on intelligent techniques in medical data security.

A Conference on the Theory and Application of Cryptographic Techniques, Held at he University of California, Santa Barbara, through the Co-operation of the Computer Science Department, August 18 - 220, 1985

Cryptology: Classical and Modern, Second Edition proficiently introduces readers to the fascinating field of cryptology. The book covers classical methods including substitution, transposition, Playfair, ADFGVX, Alberti, Vigene re, and Hill ciphers. It also includes coverage of the Enigma machine, Turing bombe, and Navajo code. Additionally, the book presents modern methods like RSA, ElGamal, and stream ciphers, as well as the Diffie-Hellman key exchange and Advanced Encryption Standard. When possible, the book details methods for breaking both classical and modern methods. The new edition expands upon the material from the first edition which was oriented for students in non-technical fields. At the same time, the second edition supplements this material with new content that serves students in more technical fields as well. Thus, the second edition can be fully utilized by both technical and non-technical students at all levels of study. The authors include a wealth of material for a one-semester cryptology course, and research exercises that can be used for supplemental projects. Hints and answers to selected exercises are found at the end of the book.

Crypto 2001, the 21st Annual Crypto conference, was sponsored by the Int- national Association for Cryptologic Research (IACR) in cooperation with the IEEE Computer Society Technical Committee on Security and Privacy and the Computer Science Department of the University of California at Santa Barbara. The conference received 156 submissions, of which the program committee selected 34 for presentation; one was later withdrawn. These proceedings contain the revised versions of the 33 submissions that were presented at the conference. These revisions have not been checked for correctness, and the authors bear full responsibility for the contents of their papers. The conference program included two invited lectures. Mark Sherwin spoke on, \Quantum information processing in semiconductors: an experimentalist’s view." Daniel Weitzner spoke on, \Privacy, Authentication & Identity: A recent history of cryptographic struggles for freedom." The conference program also included its perennial \rump session," chaired by Stuart Haber, featuring short, informal talks on late{breaking research news. As I try to account for the hours of my life that ?ew o to oblivion, I realize that most of my time was spent cajoling talented innocents into spending even more time on my behalf. I have accumulated more debts than I can ever hope to repay. As mere statements of thanks are certainly insu cient, consider the rest of this preface my version of Chapter 11.
