Mutual Authentication with Dynamic Keys in an IEEE802.16e PKM Environment

In this paper, we propose a novel communication authentication method, called mutual authentication with dynamic keys (MAWDK for short) which provides wireless communication with a mutual authentication and dynamic keys, and with which a subscriber station (SS) and a base station (BS) individually input random numbers to the Diffie-Hellman Public Key Distribution System (DH-PKDS for short) to generate a set of public keys and a set of common secret keys as the strong data connection for authentication (DCA) between the two stations. The SS and BS authenticate each other by using the identity certification keys. Plaintext is encrypted by the method of two-dimensional stream cipher so that cipher text can be more efficiently and securely transmitted.
