Fully Anonymous Group Signatures Without Random Oracles
We construct a new group signature scheme using bilinear groups. The group signature scheme is practical, both keys and group signatures consist of a constant number of group elem...

A Universally Composable Scheme for Electronic Cash
We propose a scheme for electronic cash based on symmetric primitives. The scheme is secure in the framework for universal composability assuming the existence of a symmetric CCA2-...

Towards a Concrete Security Proof of Courtois, Finiasz and Sendrier Signature Scheme
Abstract. Courtois, Finiasz and Sendrier proposed in 2001 a practical code-based signature scheme. We give a rigorous security analysis of a modified version of this scheme in the...

A Directed Signature Scheme Based on RSA Assumption
A directed signature scheme allows a designated verifier to directly verify a signature issued to him, and a third party to check the signature validity with the help of the signe...
