Title:
Constant Size Traceable Ring Signature Scheme without Random Oracles
Authors: Ke Gu, Na Wu
Abstract:Currently several traceable (or linkable) identity-based ring signature schemes have been proposed. However, most of them are constructed in the random oracle model. In this paper, we present a fully traceable ring signature (TRS) scheme without random oracles, which has the constant size signature and a security reduction to the computational Diffie-Hellman (CDH) assumption. Also, we give a formal security model for traceable ring signature and prove that the proposed scheme has the properties of traceability and anonymity.
