Cryptanalysis of pairing-free certificateless authenticated key agreement protocol

Zhian Zhu

Abstract

Recently, He et al. [D. He, J. Chen, J. Hu, A pairing-free certificateless authenticated key agreement protocol, International Journal of Communication Systems, 25(2), pp. 221-230, 2012] proposed a pairing-free certificateless authenticated key agreement protocol and demonstrated that their protocol is provable security in the random oracle model. However, in this paper, we show that t He et al. protocol is completely broken.
