This article presents optimization results on the recent MOVA undeniable signature scheme presented by Monnerat and Vaudenay at PKC ’04 as well as its generalization proposed at ...
Klimov and Shamir proposed a new class of simple cryptographic primitives named T-functions. For two concrete proposals based on the squaring operation, a single word T-function an...
In this paper we produce a practical and efficient algorithm to find a decomposition of type n = k i=1 2si 3ti , si, ti ∈ N ∪ {0} with k ≤ c + o(1) ¡ log n log log n ....
Recently, some collisions have been exposed for a variety of cryptographic hash functions [20,21] including some of the most widely used today. Many other hash functions using simi...
