The acceptance and adoption of technologies also depend on security.<br>Therefore, this article shows security vulnerabilities found in WiMAX and gives possible solutions to eliminate them.<br>We find the initial network procedure is not effectively secured that makes man-in-the-middle attack possible.<br>Focusing on this attack, we propose Diffie-Hellman (DH) key exchange protocol to enhance the security level during<br>network initialization. We modify DH key exchange protocol to fit it into mobile WiMAX network as well as to<br>eliminate existing weakness in original DH key exchange protocol. Finally we found that the proposed algorithm<br>shows 2.5 times better performance in comparison with existing systems.</p&gt;}, number={1}, journal={MIST INTERNATIONAL JOURNAL OF SCIENCE AND TECHNOLOGY}, author={Mir Md.
