Reminder Subject: TALK: TOC Seminar: Identity-Based Encryption from the Diffie-Hellman Assumption by Sanjam Garg - Tuesday, September 19 at 4pm

Abstract: In this talk, I will describe a new construction of identity-based encryption based on the hardness of the (Computational) Diffie-Hellman Problem (without using groups with pairings). This construction achieves the standard notion of identity-based encryption as considered by Boneh and Franklin [CRYPTO 2001]. The presented construction bypasses known impossibility results using garbled circuits that make a non-black-box use of the underlying cryptographic primitives.
