  Abstract

Devising a secure authenticated key agreement (AKA) protocol for two entities communicating over an open network is a matter of current research. McCullagh et al. proposed a new two-party identity-based AKA protocol supporting both key escrow and key escrow-less property instantiated by either in a single domain or over two distinct domains. In this paper, we show that their protocol over two distinct domains suffers from masquerading attack and therefore does not satisfy the claimed security. The attack is made possible due to the lack of sufficient authentication of entity and integrity assurance in the protocol. We then propose an efficient verifiable key agreement protocol by including signature primitive in the authentication procedure to solve the problem of McCullagh et al."s protocol.
