Some Identity Based Strong Bi-Designated Verifier Signature Schemes
Sunder Lal and Vandani Verma
Abstract: The problem of generalization of (single) designated verifier schemes to several designated verifiers was proposed by Desmedt in 2003. The paper proposes eight new Identity Based Strong Bi-Designated Verifier Signature Schemes in which the two designated verifiers may not know each other. The security and the computational efficiency of the schemes are also analyzed.
Category / Keywords: ID based cryptography, multi-designated verifier, bilinear pairing, hash functions.
