Strengthened Security for Blind Signatures
Abstract. Provable security is a very nice property for cryptographic protocols. Unfortunately, in many cases, this is at the cost of a considerable loss in terms of efficiency. Mo...

Security Arguments for Digital Signatures and Blind Signatures
Abstract. Since the appearance of public-key cryptography in the seminal DiffieHellman paper, many new schemes have been proposed and many have been broken. Thus, the simple fact t...

Defeating Malicious Servers in a Blind Signatures Based Voting System
In this paper, we present two failures in the blind signatures based voting system Votopia [2] which has been tested during the last World Soccer Cup. We then propose a fix which r...
