Security in IEEE 802.16m

Several changes and enhancements are introduced in the amendment for IEEE 802.16m. Figure 8.2 shows the counterpart for the security sublayer in .16m, called the Security Architecture.

Within the AMS and the ABS security architecture, there are two logical entites: the security management entity and the encryption and integrity entity.

The security management entity functions include:

• Overall security management and control;
• EAP encapsulation/decapsulation for authentication;
• Privacy Key Management (PKM) control (e.g., key generation/derviation/distribution, key state management);
• Authentication and Security Association (SA) control; and
• Location Privacy.
