EAP-AKA' is now available in FreeRADIUS v4.0.x HEAD. All optional components are supported except fast re-authentication which'll be added soon. In addition to EAP-AKA' FreeRADIUS can now perform the duties of an AuC, generating AKA quintuplets and SIM triplets using a subscriber key (Ki) and a derived operator code (OPc). The AuC SIM algorithms available for EAP-SIM are: - COMP128v1 - COMP128v2 - COMP128v3 - COMP128v4 (Milenage) The AuC SIM algorithms available for EAP-AKA are: - Milenage In most cases this functionality should only be used for testing, and the rlm_sigtran module, rlm_rest module or a diameter proxy should be used to acquire triplets or quintuplets. If anyone knows of any other extensions to EAP-SIM, EAP-AKA or EAP-AKA['], or additional SIM algorithms they'd like implemented, let me know and i'll see if I can add them in. -Arran Arran Cudbard-Bell <a.cudbardb@freeradius.org> FreeRADIUS Development Team FD31 3077 42EC 7FCD 32FE 5EE2 56CF 27F9 30A8 CAA2
