Abstract :
In this paper, we study strong designated verifier signature in certificateless public key settings. We first present the notion and security model of certificatless strong designated verifier signature (CLSDVS) scheme, and then, we provide a concrete CLSDVS scheme, which has short signature size and low computational cost, satisfies all the requirements of strong designated verifier signature. The scheme is proven secure in the random oracle model by assuming the intractability of the Computational Bilinear Diffie-Hellman Problem and the Computational Diffie-Hellman Problem.
