Technieques for deriving security keys for a cellular network based on performance of an extensible authentication protocol (eap) procedure

A user equipment (UE) comprising:

• a transceiver configured to access a network having a network type;
• memory;
• and
• a processor;
• wherein the memory and processor are configured to:
• authenticate with an authentication server as part of an extensible authentication protocol (EAP) procedure;
• and
• in response to the network type being a first network type, use a master session key (MSK) for the EAP procedure, wherein the MSK is derived at the UE based at least in part on one or more parameters associated with the MSK and selected from the group consisting of:
• an identifier, a random number, a network parameter, and a UE parameter, and further based at least in part on one or more authentication credentials associated with the MSK for the EAP procedure.

A user equipment (UE) comprising:

• means for accessing a network having a network type;
• means for authenticating with an authentication server as part of an extensible authentication protocol (EAP) procedure;
• means for deriving a master session key (MSK) and an extended master session key (EMSK) for the EAP procedure at the UE, wherein the MSK and the EMSK are derived based at least in part on one or more parameters selected from the group consisting of:
• an identifier, a random number, a network parameter, and a UE parameter, and further based at least in part on one or more authentication credentials for the EAP procedure;
• and
• means for performing at least one authentication procedure with the network, wherein the at least one authentication procedure is based on an association of the MSK or the EMSK with the network type.
