IETF RFC 8940 PDF

Abstract

RFC 5247 is updated to define and clarify EAP Session-Id derivation for multiple Extensible Authentication Protocol (EAP) methods. The derivation of Session-Id was not given for EAP Subscriber Identity Module (EAP-SIM) or EAP Authentication and Key Agreement (EAP-AKA) when using the fast reconnect exchange instead of full authentication. The derivation of Session-Id for full authentication is clarified for both EAP-SIM and EAP-AKA. The derivation of Session-Id for Protected EAP (PEAP) is also given. The definition for PEAP follows the definition for other TLS-based EAP methods.
