Round complexity is a central measure of efficiency, and characterizing the round complexity of various cryptographic tasks is of both theoretical and practical importance. We show...
Millions of citizens around the world have already acquired their new electronic passport. The e-passport is equipped with contactless communication capability, as well as with a s...
Abstract. Algorithmic progress and future technology threaten today’s cryptographic protocols. Long-term secure protocols should not even in future reveal more information to a...
Web Services are the basic building blocks of next generation Internet applications, based on dynamic service discovery and composition. Dedicated discovery services will store bot...
We address the problem of using untrusted (potentially malicious) cryptographic helpers. We provide a formal security definition for securely outsourcing computations from a comp...
