Specification for use of EAP EMSK in deriving Mobile IP root keys

Specification for use of EAP EMSK in deriving Mobile IP root keys Huawei USA Huawei Technologies [USRK] proposes a new mechanism for deriving cryptographically separate usage specific root keys (USRK) from the EAP extended master session key (EMSK). This document follows the procedure suggested in [USRK] to derive root keys for Mobile IPv4, Mobile IPv6, and proxy Mobile IP.
