Progress in Cryptology - VIETCRYPT 2006

Zusammenfassung

This book constitutes the thoroughly refereed post-proceedings of the First International Conference on Cryptology in Vietnam, VIETCRYPT 2006, held in Hanoi, Vietnam, September 2006. The 25 papers cover signatures and lightweight cryptography, pairing-based cryptography, algorithmic number theory, ring signatures and group signatures, hash functions, cryptanalysis, key agreement and threshold cryptography, as well as public-key encryption.
