Abstract :
In this paper, we present a two-party key agreement protocol, which is secure in standard model. By using the Goldreich-Levin hardcore predicate, we reduce the security of our scheme to Computational Bilinear Diffie-Hellman assumption, and a proof is given. Furthermore, with the consistency of messages exchanged publicly verifiable, our scheme achieves most of the known security attributes.
