Certificateless One-Way Authenticated Two-Party Key Agreement Protocol

Abstract

Key agreement is one of the fundamental cryptographic primitives in public key cryptography. It plays an important role for securing systems in practice. In this paper, we present the first certificateless One-Way authenticated Two-Party key agreement protocol. The security of the proposed protocol is analyzed based on the intractability of the standard discrete logarithm (DL) and bilinear Diffie-Hellman (BDH) problems. For efficiency, our protocol enjoys low complexity in both communication and computation.
