In the last ten years, multivariate cryptography has emerged as a possible alternative to public key cryptosystems based on hard computational problems from number theory. Notably,...
Abstract Lattice reduction is a hard problem of interest to both publickey cryptography and cryptanalysis. Despite its importance, extremely few algorithms are known. The best algo...

We build concurrently executable blind signatures schemes in the common reference string model, based on general complexity assumptions, and with optimal round complexity. Namely, ...
Abstract. In this paper, we study the security of 2Rschemes [17,18], which are the "minus variant" of two-round schemes. This variant consists in removing some of the n p...
We present the first general protocol for secure multiparty computation which is scalable, in the sense that the amortized work per player does not grow, and in some natural settin...
Abstract. We study unconditionally secure 1-out-of-2 Oblivious Transfer (1-2 OT). We first point out that a standard security requirement for 1-2 OT of bits, namely that the receiv...
