We construct an efficient and novel identity-based strong designated verifier signature (IBSDVS) scheme based on bilinear pairings, and provide the security proofs and efficiency analysis for the proposed scheme. Our IBSDVS scheme achieves higher efficiency and satisfies all the security requirements of the designated verifier signatures in identity-based cryptography.

Proxy multi-signature is an extension of the basic proxy signature primitive, and permits two or more entities to delegate their signing capabilities to the same other entity. Combining proxy multi-signature with identity based cryptography, in this paper, We construct a concrete identity based proxy multi-signature scheme by using bilinear pairings. Analysis shows that the scheme is capable of resisting forgery attack and can satisfy all the required security properties of a proxy signature. Furthermore, the new scheme is very simple and efficient computationally. It has the property that the size of a proxy multi-signature is independent of the number of the original signers.
