This book constitutes the refereed proceedings of the first International Theory of Cryptography Conference, TCC 2004, held in Cambridge, MA, USA in February 2004.
The 28 revised full papers presented were carefully reviewed and selected from 70 submissions. The papers constitute a unique account of original research results on theoretical and foundational topics in cryptography; they deal with the paradigms, approaches, and techniques used to conceptualize, define, and provide solutions to natural cryptographic problems.
