This book constitutes the thoroughly refereed postproceedings of the 10th Annual International Workshop on Selected Areas in Cryptography, SAC 2003, held in Ottawa, Canada, in August 2003.
The 25 revised full papers presented were carefully selected from 85 submissions during two rounds of reviewing and improvement. The papers are organized in topical sections on elliptic and hyperelliptic curves, side channel attacks, security prools and applications, cryptanalysis, cryptographic primitives, stream ciphers, and efficient implementations.
