A number of signature schemes and standards have been recently designed, based on the Discrete Logarithm problem. In this paper we conduct design validation of such schemes while t...

The first practical public key cryptosystem to be published, the Diffie-Hellman key exchange algorithm, was based on the assumption that discrete logarithms are hard to compute. T...
Undeniable signature has been extensively researched after Chaum and Antwerpen first proposed the concept of this special digital signature ten years ago. Up to now, however, almo...
Distributed key generation is one of the most challenging tasks for threshold cryptosystems. Designing such a protocol and proving its security against a malicious, adaptive adver...
For the two last decades, electronic authentication has been an important topic. The first applications were digital signatures to mimic handwritten signatures for digital document...
