Constructing practical and provably secure group signature schemes has been a very active research topic in recent years. A group signature can be viewed as a digital signature wit...
We introduce a new computational problem related to the interpolation of group homomorphisms which generalizes many famous cryptographic problems including discrete logarithm, Diï¬...
In this paper, we present a novel protocol, called Distributed Signcryption with Verifiable Partial Signature (DiSigncryption) protocol, to allow an agent owner to securely distrib...
We propose a dynamic accumulator scheme from bilinear pairings, whose security is based on the Strong Diffie-Hellman assumption. We show applications of this accumulator in constru...
We answer the open question of the possibility of building a digital signature scheme with proven security based on the one-wayness of a trapdoor permutation and with signatures as...
