This document provides an overview of security issues in WiMAX networks and proposes solutions. It discusses three main security goals in wireless networks: confidentiality, integrity, and authentication. It then describes WiMAX security architecture, including data link layer security with encryption sublayers, and protocol layer security schemes like RSA authentication and EAP authentication. Potential threats to WiMAX security are outlined, such as rogue base stations, DoS attacks, man-in-the-middle attacks, and threats in the physical layer like blocking and rushing. Finally, conclusions are drawn about precautions taken in WiMAX compared to earlier wireless standards.
