Secure authentication and key management protocols for mobile multihop WiMAX networks by Fisal, Norsheila, Abu Bakar, Zurkarmawan, Salawu, Nathaniel, Ullah, Rahat, Safdar, Hashim, Khan, Adnan Shahid

“…However, the protocol still faces several security threats, specifically Denial of Service (DoS), replay attacks, Man in the Middle (MitM) attacks and the interleaving attacks, which is termed as Medium Access Control (MAC) layer attacks. This paper proposed a modified version PKM protocol for both unilateral and mutual authentication, which is termed as Self-organized Efficient Authentication and Key Management Scheme (SEAKS) authentication protocol. …”
