A system and method for enforcing digital rights management (DRM) rules in a terminal, even when the requesting rendering application is already operating. Content, which may be encrypted, is received at the terminal and securely stored. On-demand authorization is effected for the rendering application that is requesting access to the content, using secure communications between a DRM engine within the terminal and an operating system within the terminal that is augmented with a security manager adapted to engage in such secure communications. If the rendering application is found to be authorized, the DRM rules are applied to determine whether the rendering application may access the content, and if so, the content is made available to the rendering application.

System and method for dynamically enforcing digital rights management rules

The security keys in the mobile terminals and access points of a wireless local area network (WLAN) are created, utilized and managed for a communication session between a mobile terminal and access point. Both the WLAN link level security protection and IP security functions of the network use the same Internet Key Exchange (IKE) key management protocol and use certificates in the same certificate hierarchy. When the mobile terminals associates with the network, it uses the IKE protocol with private keys and certificates to generate WLAN link level keys with the access point and provide mutual authentication.
