Abstract

Key agreement is a fundamental activity to establish communication between two parties. Kim et al. (2013) proposed a CertificateLess two-party authenticated key agreement (CTAKA) protocol, which is secure in extended Canetti-Krawczyk (eCK) model. This paper describes the security flaw of Kim et al.'s CTAKA protocol, which is found vulnerable against Key-Compromise Impersonation (K-CI) attack. For the resistance of the attack in Kim et al.'s CTAKA protocol, a defensive measure has been proposed, which is secure in eCK model.
