A Novel Secure Authenticated Key Exchange Protocol for Wireless Sensor Networks


Tamer Barakat


Vol. 12  No. 12  pp. 136-140


Recently, Eun-Jun et al.'s proposed an improvement of the authentication key exchange protocol. In their protocol, they proved that neither Hung et al.’s nor Tian et al.’s provide perfect forward secrecy, and present an improved protocol in order to address this problem. In this paper, we will demonstrate some security leaks inherent in Eun-Jun et al.'s protocol and show that this protocol is still suffers from perfect forward secrecy problem. Finally, we will propose a new Secure Authenticated Key Exchange (SAKE) protocol to eliminate the pointed out security leaks.
