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 ...
Abstract. In this paper, we propose a signcryption scheme which provides all the following properties at the same time. (1) forward security: the private key of a sender does not h...
A New digital signature scheme based on Stepwise Triangular Scheme (STS) is proposed. The proposed trapdoor has resolved the vulnerability of STS and secure against both Gr¨obner ...
We provide an alternative method for constructing lattice-based digital signatures which does not use the “hash-and-sign” methodology of Gentry, Peikert, and Vaikuntanathan (ST...
We present the first efficient group signature scheme that is provably secure without random oracles. We achieve this result by combining provably secure hierarchical signatures i...
