AKA in UMTS
AKA is a mechanism which performs authentication and session key distribution in Universal Mobile Telecommunications System (UMTS) networks. AKA is a challenge-response based mechanism that uses symmetric cryptography. AKA is typically run in a UMTS IP Multimedia Services Identity Module (ISIM), which resides on a smart card like device that also provides tamper resistant storage of shared secrets. AKA is defined in RFC 3310.
AKA in WiMAX
AKA is also specified for WiMAX (IEEE 802.16m), based on the Extensible Authentication Protocol (EAP).
