This book constitutes the refereed proceedings of the 8th International Conference on Cryptology and Network Security, CANS 2009, held in Kanazawa, Japan, in December 2009. The 32 revised full papers presented together with 3 invited talks were carefully reviewed and selected from 109 submissions. The papers are organized in topical sections on cryptographic protocols and schemes; cryptanalysis; wireless and sensor security; network security; privacy and anonymity; functional and searchable encryption; authentication; block cipher design; and algebraic and number-theoretic schemes.

The4thInternationalConferenceonPairing-BasedCryptography(Pairing2010) was held in Yamanaka Hot Spring, Japan, during December 13-15, 2010. It was jointly co-organized by the National Institute of Advanced Industrial Science and Technology (AIST), Japan, and the Japan Advanced Institute of Science and Technology (JAIST). The goal of Pairing 2010 was to bring together leading researchersand pr- titioners from academia and industry, all concerned with problems related to pairing-based cryptography. We hope that this conference enhanced com- nication among specialists from various research areas and promoted creative interdisciplinary collaboration. Theconferencereceived64submissionsfrom17countries,outofwhich25- pers from 13 countries 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 externalreviewersjoinedthereviewprocessintheirparticularareasofexpertise.We were fortunate to have this energetic team of experts, and are deeply gra- ful to all of them for their hard work, which included a very active discussion phase. The paper submission, review and discussion processes were e?ectively and e?ciently made possible by the Web-based system iChair. Furthermore,theconferencefeaturedthreeinvitedspeakers:JensGrothfrom University College London, Joseph H. Silverman from Brown University, and Gene Tsudik from University of California at Irvine, whose lectures on cutti- edge research areas- "Pairing-Based Non-interactive Zero-Knowledge Proofs," "A Survey of Local and Global Pairings on Elliptic Curves and Abelian Va- eties," and "Some Security Topics with Possible Applications for Pairing-Based Cryptography," respectively- contributed in a signi?cant part to the richness of the program.

This book constitutes the proceedings of the 19th International Conference on Provable and Practical Security, ProvSec 2025, which took place in Yokohama, Japan, during October 10–12, 2025.The 22 full papers, 3 short papers and 5 posters included in this book were carefully reviewed and selected from 72 submissions. They were organized in topical sections as follows: digital signature; post-quantum cryptography; machine learning security and privacy; cryptographic protocol; searchable encryption; cryptanalysis; distributed system and blockchain security; short papers; and posters.set programming; functional programming; languages, methods and tools; and declarativesolutions.
