This book constitutes the refereed proceedings of the 6th International Conference on the Theory and Application of Cryptographic Techniques in Africa, AFRICACRYPT 2013, held in Cairo, Egypt, in June 2013. The 26 papers presented were carefully reviewed and selected from 77 submissions. They cover the following topics: secret-key and public-key cryptography and cryptanalysis, efficient implementation, cryptographic protocols, design of cryptographic schemes, security proofs, foundations and complexity theory, information theory, multi-party computation, elliptic curves, and lattices.

This book constitutes the proceedings of the 21st International Conference on Selected Areas in Cryptography, SAC 2014, held in Montreal, QC, Canada, in August 2014.
The 22 papers presented in this volume were carefully reviewed and selected from 103 submissions. There are four areas covered at each SAC conference. The three permanent areas are: design and analysis of symmetric key primitives and cryptosystems, including block and stream ciphers, hash function, MAC algorithms, cryptographic permutations, and authenticated encryption schemes; efficient implementations of symmetric and...
