This book constitutes the refereed proceedings of the 24th Annual International Conference on the Theory and Applications of Cryptographic Techniques, EUROCRYPT 2005, held in Aarhus, Denmark in May 2005. The 33 revised full papers presented were carefully reviewed and selected from 190 submissions. The papers are organized in topical sections on cryptanalysis, theory, encryption, signatures and authentication, algebra and number theory, quantum cryptography, secure protocols, and broadcast encryption and traitor tracing.
