题目: Cryptographic Reverse Firewall via Malleable Smooth Projective Hash Functions
地 点： 北校区新科技楼1012
Abstract: Motivated by the revelations of Edward Snowden, post-Snowden cryptography has become a prominent research direction in recent years. In Eurocrypt 2015, Mironov and Stephens-Davidowitz proposed a novel concept named cryptographic reverse firewall which can resist exhilaration of secret information from an arbitrarily compromised machine. In this talk, I will present generic constructions for several widely used cryptographic protocols based on a new notion named malleable smooth projective hash function and demonstrate the feasibility of the new notion using graded rings. I will present an instantiation from the k-linear assumption and show how to generically construct cryptographic reverse firewall via a malleable smooth project hash function in a modular way for some widely used cryptographic protocols.
