Privacy Sub Layer Threats to WiMAX Technology

Privacy Sub layer’s main objective was to protect service providers against theft of service, rather than securing network users. It is obvious that the privacy sub layer only secures data at the data link layer, but it does not ensure complete encryption of user data. Furthermore, it does not protect physical layer from being interrupted. It is essential to include technologies to secure physical layer and higher layer security for a converged routable network and devices within the system. (Derrick Boom, 2004)
