This Week's CIS Seminar
Date:	 Friday, October 14, 2011
Time:	 10:30 a.m.
Place:	 32-G449
Speaker: Rafael Pass, Cornell University
Title: 	 Limits of Provable Security from Standard Assumptions
 We show that the security of some well-known cryptographic
protocols, primitives and assumptions (e.g., the Schnorr
identification scheme, commitments secure under adaptive selective
decommitment, the one-more discrete logarithm assumption) cannot
be based on any standard intractability assumption using a Turing
(i.e., black-box) reduction. This result holds even if the protocol
makes non-black-box use of the underlying assumption.
