The paper presents security enhancement of Worldwide Interoperability for Microwave Access (WiMAX) for authentication frame work in IEEE 802.16 against man-in-the-middle attack. This gives secure authentication of legitimate Mobile Station (MS) and protects man-in-the-middle attack. To prevent this kind of attack and to make the authentication more secure, a Hash-Random model have proposed. This model is based on hash function algorithm and pseudo random number. In the paper, firstly an overview of authentication framework briefly discussed. Then, the proposed method is described in detail. Finally, simulation results are examined in order to highlight the performance of the method.
