Abstract :
A password-authenticated key agreement scheme based on elliptic curves cryptography (ECC) for ad hoc networks is presented. The scheme is composed of system initialization, identity-based (ID-based) password evolvement algorithm, identity authentication algorithm and session keys generation algorithm. The freshness and security of password are guaranteed by the sharing password evolvement mechanism every time in node´s identity authentication. The self-certified key is used in the scheme to guarantee the reliability of the node´s identity and reduce requirement for data storage and traffic. The scheme combines password authentication with public key authentication and enjoys many secure properties such as forward security, backward security, key independence, etc. So that it can resist types of attack. The computation complexity and the communication overhead of the scheme are low. The scheme is independent of any group controller and is suitable for ad hoc networks.
