Abstract: | In this paper, we propose a universal forgery attack on Kang et al.'s identity-based strong designated verifier signature (IBSDVS) scheme. We show any one can forge a valid IBSDVS on an arbitrary message without the knowledge of the private key of either the signer or the designated verifier. |
