This book constitutes the thoroughly refereed postproceedings of the 7th International Conference on Information Security and Cryptology, ICISC 2004, held in Seoul, Korea in December 2004. The 34 revised full papers presented have gone through two rounds of reviewing and improvement and were selected from 194 submissions. The papers are organized in topical sections on block ciphers and stream ciphers, public key cryptosystems, PKI and related implementations, digital signatures, elliptic curve cryptosystems, provable security and primitives, network security, steganography, and biometrics.
