Apparatus and method for signaling enhanced security context for session encryption and integrity keys

A remote station, comprising:

• means for forwarding a first message to a serving network, wherein the first message includes an information element signaling that the remote station supports a first security context, and wherein the first security context has a security property that is not supported by a second security context;
• means for generating at least one session key, in accordance with the first security context, using the information element;
• means for receiving, in response to the first message, a second message having an indication that the serving network supports the first security context;
• and
• means for having wireless communications, in response to the second message, protected by the at least one session key.

A remote station, comprising:

• a processor configured to:
• forward a first message to a serving network, wherein the first message includes an information element signaling that the remote station supports a first security context, and wherein the first security context has a security property that is not supported by a second security context;
• generate at least one session key, in accordance with the first security context, using the information element;
• receive, in response to the first message, a second message having an indication that the serving network supports the first security context;
• and
• have wireless communications, in response to the second message, protected by the at least one session key.

A computer program product, comprising:

• computer-readable storage medium, comprising:
• code for causing a computer to forward a first message to a serving network, wherein the first message includes an information element signaling that the computer supports a first security context, and wherein the first security context has a security property that is not supported by a second security context;
• code for causing a computer to generate at least one session key, in accordance with the first security context, using the information element;
• code for causing a computer to receive, in response to the first message, a second message having an indication that the serving network supports the first security context;
• and
• code for causing a computer to have wireless communications, in response to the second message, protected by the at least one session key.
