The certificateless authenticated key agreement proto-col proposed by Mandt et al does not have the property of key-compromise impersonation (K-CI) resilience. An improved protocol with a simple modification of their protocol is proposed in this paper. In particular,our improved protocol is proved to be immune to the K-CI attack and at the same time possess other security properties.
