WiMAX (Worldwide Interoperability for Microwave Access) is a wireless broadband technology, which supports point to multi-point (PMP) broadband wireless access. WiMAX Networks provides wireless communications with high quality of service. In the E-Learning System using WiMAX networks, the users of the subscriber station must be authenticated. The authentication in WiMAX is performed using Extensible Authentication Protocol. The EAP protocol based on Privacy Key Management in WiMAX is susceptible to security problems. In this paper the security mechanisms for authentication, encryption, and availability and its potential threats for E-Learning Systems is analyzed.
