Abstract. We construct the first O(1)-size designated confirmer signatures (DCS) with security in the state-of-the-art model of Camenisch and Michels, Eurocrypt 2000, without rando...
We present an index-calculus algorithm for the computation of discrete logarithms in the Jacobian of hyperelliptic curves defined over finite fields. The complexity predicts that i...
In this paper we present a new scheme for constructing universal one-way hash functions that hash arbitrarily long messages out of universal one-way hash functions that hash fixed...
