Identity Based Strong Bi-Designated Verifier Proxy Signature Schemes

Sunder Lal and Vandani Verma

Abstract

Proxy signature schemes allow delegation of signing rights. The paper proposes the notion of Identity Based Strong Bi-Designated Verifier Proxy Signature (ID-SBDVPS) schemes. In such schemes, only the two designated verifiers can verify that the proxy signer on behalf of the original signer signed the message but none of them is able to convince anyone else of this fact. The paper proposes nine such schemes and analyses the computational efficiency of each.
