A Secure MAKAP for Wireless Communication

A mutual authentication and key establishment protocol proposed by Aydos et al, for wireless communication based on elliptic curve cryptography can provide authentication between the user and server and they agreement a session key in the end of it. Unfortunately, Mangipudi pointed out Aydos’ scheme was incurred the man-in-middle attack denial-of-service attack and impersonation based on man-in-middle attack. Then he proposed an improved scheme to overcome the above weakness. However, there is an attack which can forge the message required in the protocol and impersonation a valid user to the server.
