The papers are organized in topical sections on stream ciphers, cryptographic hash functions, public-key cryptography, security protocols, hardware attacks, block ciphers, cryptographic hardware, elliptic curve cryptography, and threshold cryptography.

This book constitutes the refereed proceedings of the 7th International Conference on Cryptology in India, INDOCRYPT 2006, held in Kolkata, India in December 2006. The 29 revised full papers and 2 invited papers cover such topics as symmetric cryptography, provable security, fast implementation of public key cryptography, id-based cryptography, as well as embedded systems and side channel attacks.

The INDOCRYPT series of conferences started in 2000. INDOCRYPT 2004 was the ?fth one in this series. The popularity of this series is increasing every year. The number of papers submitted to INDOCRYPT 2004 was 181, out of which 147 papers conformed to the speci?cations in the call for papers and, therefore, were accepted to the review process. Those 147 submissions were spread over 22 countries. Only 30 papers were accepted to this proceedings. We should note that many of the papers that were not accepted were of good quality but only the top 30 papers were accepted. Each submission received at least three independent - views. The selection process also included a Web-based discussion phase. We made e?orts to compare the submissions with other ongoing conferences around the world in order to ensure detection of double-submissions, which were not - lowed by the call for papers. We wish to acknowledge the use of the Web-based review software developed by Bart Preneel, Wim Moreau, and Joris Claessens in conducting the review process electronically. The software greatly facilitated the Program Committee in completing the review process on time. We would like to thank C ́ edric Lauradoux and the team at INRIA for their total support in c- ?guring and managing the Web-based submission and review softwares. We are unable to imagine the outcome of the review process without their participation. This year the invited talks were presented by Prof. Colin Boyd and Prof.

The papers are organized in topical sections on side-channel attacks, secret-key cryptography, hash functions, pairings, and protocols.

The 7th International Conference on Information Security and Cryptology was organized by the Korea Institute of Information Security and Cryptology (KIISC) and was sponsored by the Ministry of Information and Communication of Korea.

This book constitutes the refereed proceedings of the 17th International Conference on Cryptology in India, INDOCRYPT 2016, held in Kolkata, India, in December 2016. The 23 revised full papers presented in this book were carefully reviewed and selected from 84 submissions. The focus of the conference includes works on Public-Key Cryptography, Cryptographic Protocols, Side-Channel Attacks, Implementation of Cryptographic Schemes, Functional Encryption, Symmetric-Key Cryptanalysis, Foundations, and New Cryptographic Constructions.

This second volume addresses tremendous progress in elliptic curve cryptography since the first volume.
