Security Flaws in Several Group Signatures Proposed by Popescu
In resent years, Popescu proposed several group signature schemes based on the Okamoto-Shiraishi assumption in [8–11], and claimed his schemes are secure. However, this paper dem...

Extracting Group Signatures from Traitor Tracing Schemes
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...
