Summary: Zero knowledge turned out to be a useful tool for many cryptographic applications. Many cryptographic protocols based on bilinear pairings, namely Weil and Tate pairings, have been proposed recently. In this paper, first elliptic curves and Weil pairing are introduced. In addition, a new zero-knowledge identification scheme based on Weil pairing is proposed. Finally, our scheme is compared with some other identification schemes. We also describe the zero-knowledge property of the proposed scheme and give a security analysis of it.
