We study proactive two-party signature schemes in the context of user authentication. A proactive two-party signature scheme (P2SS) allows two partiesāthe client and the serverā...

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...

Round complexity is a central measure of eļ¬ciency, and characterizing the round complexity of various cryptographic tasks is of both theoretical and practical importance. We show...
The design of cryptographic hash functions is a very complex and failure-prone process. For this reason, this paper puts forward a completely modular and fault-tolerant approach to...
Exposure of secret keys seems to be inevitable, and may in practice represent the most likely point of failure in a cryptographic system. Recently, the notion of intrusion-resilien...
