Amongst provably secure signature schemes, two distinct classes are of particular interest: the ones with tight reduction (e.g., RSA-PSS), and those which support the use of coupon...
Abstract. We give improved upper bounds on the communication complexity of optimally-resilient secure multiparty computation in the cryptographic model. We consider evaluating an n...
Abstract. The use of passwords in security protocols is particularly delicate because of the possibility of off-line guessing attacks. We study password-based protocols in the cont...
Abstract. This paper describes the analysis of Pull-Based Asynchronous Rekeying Framework (ARF), a recently proposed solution to the scalable group key management problem in secure...
