Abstract

In 2004, Aslan presented a novel protocol for authentication and key distribution, named AUTHMAC_DH. The proposed AUTHMAC_DH protocol aims to achieve a comparable performance with the Kerberos protocol and to improve its weaknesses. Based on the AUTHMAC_DH protocol developed by Aslan, a communication-efficient AUTHMAC_DH protocol is proposed in this investigation. The computation cost of the proposed protocol is equal to that of the AUTHMAC_DH protocol of Aslan. The proposed communication-efficient AUTHMAC_DH protocol also achieves the goals of authentication and key distribution. However, the numbers of messages and rounds in communication are fewer than those of the protocol of Aslan.
