This book constitutes the thoroughly refereed post-proceedings of the First International Conference on Cryptology in Vietnam, VIETCRYPT 2006, held in Hanoi, Vietnam, in September 2006.
The 24 revised full papers presented together with 1 invited paper were carefully reviewed and selected from 78 submissions. The papers are organized in topical sections on 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.
