2019-11-04, rev -01: EAP Session-Id derivation has not been defined for EAP-SIM or EAP-AKA when using the fast re-authentication exchange instead of full authentication. This document updates RFC 5247 to define those derivations for EAP-SIM and EAP-AKA. Since RFC5448bis defines the Session-ID for EAP-AKA', the definition for EAP-AKA' is not included here. RFC 5247 also does not define Session-Id derivation for PEAP. A definition is given here which follows the definition for other TLS-based EAP methods.
