Due to the high computation cost of bilinear pairings, pairing-free cryptosystems have received widespread attention recently. Various pairing-free two-party key agreement protocols in the context of public key cryptography (PKC) have been studied. To avoid complex certificate management in traditional PKC and key escrow problem in identity-based ones, several certificateless cryptosystems have been proposed in this research area. In this paper, we proposed a secure and efficient certificateless pairing-free two-party key agreement protocol. In comparison with related works, our protocol requires less computational cost.
