Identity Based Strong Bi-Designated Verifier Proxy Signature Schemes
Sunder Lal Vandani Verma
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.

Some Identity Based Strong Bi-Designated Verifier Signature Schemes
Sunder Lal Vandani Verma
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.

Identity Based Strong Designated Verifier Proxy Signature Schemes
Sunder Lal Vandani Verma
The paper proposes four new ID based strong designated verifier proxy signature (SDVPS) scheme. The schemes are formed by introducing proxy in ID based SDVS, ID based in SDVPS and ID based proxy in SDVS. We have also analyzed the security of the schemes and their computation aspects.
