Title: Another Look at Provable Security: Does Tightness Matter?

Speaker: Prof. Alfred Menezes

Affiliation: University of Waterloo

Abstract: The search for mathematically rigorous security proofs for cryptographic protocols has been an important theme of researchers over the past twenty years. We discuss the question of how to interpret non-tight reductionist security proofs in cryptography, and give some examples to illustrate the subtlety and difficulty of this question. This is joint work with Neal Koblitz.
