Abstract. Digital Signatures emerge naturally from Public-Key Encryption based on trapdoor permutations, and the “duality” of the two primitives was noted as early as Diffie-He...
Abstract. One of the central lines of cryptographic research is identifying the weakest assumptions required for the construction of secure primitives. In the context of group sign...
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...
Threshold cryptosystems and signature schemes give ways to distribute trust throughout a group and increase the availability of cryptographic systems. A standard approach in design...
A potentially serious problem with current digital signature schemes is that their underlying hard problems from number theory may be solved by an innovative technique or a new gen...
