Idea behind the key agreement protocol is to enable the entities to communicate safely over insecure public networks. In this paper, we proposed a secure key agreement protocol using Diffie-Hellman key agreement. In 2005, Lee and Lee [1] proposed a key agreement protocol dependent on Diffie-Hellman and guarantee that their protocol beat the attacks like man-in-the-middle attack. However, we brought up that Lee and Lee are defenseless against man-in-the-middle attack, impersonate attack and replay attack. Further proposed an improved key agreement protocol and demonstrated that the protocol is secure against the attacks. To confirm the security properties, we have done formal verification called ProVerif tools. Finally, to demonstrate the efficient, we compared other related authentication key agreement schemes with the proposed scheme. |
