Abstract :
Recently, Lee et. al. carried out the cryptanalysis of Juang et. al. two-factor authentication key exchange protocol in Public wireless LANs. It was shown that Juang et.al. protocol is vulnerable to the stolen verifier attack and doesn´t satisfy the user anonymity. Apart from the, high computational overhead of the server. This paper, proposes an improved protocol towards authentication and key exchange based on Elliptic Curve Decision Diffie-Hellman(DDH) problem which ensures their strong resistance towards the existing weaknesses. Besides this, their security and performance analysis shows that the proposed protocol is more secure and efficient.
