2 * HLR/AuC testing gateway for hostapd EAP-SIM/AKA database/authenticator
3 * Copyright (c) 2005-2007, 2012-2013, Jouni Malinen <j@w1.fi>
5 * This software may be distributed under the terms of the BSD license.
6 * See README for more details.
8 * This is an example implementation of the EAP-SIM/AKA database/authentication
9 * gateway interface to HLR/AuC. It is expected to be replaced with an
10 * implementation of SS7 gateway to GSM/UMTS authentication center (HLR/AuC) or
11 * a local implementation of SIM triplet and AKA authentication data generator.
13 * hostapd will send SIM/AKA authentication queries over a UNIX domain socket
14 * to and external program, e.g., this hlr_auc_gw. This interface uses simple
17 * EAP-SIM / GSM triplet query/response:
18 * SIM-REQ-AUTH <IMSI> <max_chal>
19 * SIM-RESP-AUTH <IMSI> Kc1:SRES1:RAND1 Kc2:SRES2:RAND2 [Kc3:SRES3:RAND3]
20 * SIM-RESP-AUTH <IMSI> FAILURE
21 * GSM-AUTH-REQ <IMSI> RAND1:RAND2[:RAND3]
22 * GSM-AUTH-RESP <IMSI> Kc1:SRES1:Kc2:SRES2[:Kc3:SRES3]
23 * GSM-AUTH-RESP <IMSI> FAILURE
25 * EAP-AKA / UMTS query/response:
27 * AKA-RESP-AUTH <IMSI> <RAND> <AUTN> <IK> <CK> <RES>
28 * AKA-RESP-AUTH <IMSI> FAILURE
30 * EAP-AKA / UMTS AUTS (re-synchronization):
31 * AKA-AUTS <IMSI> <AUTS> <RAND>
33 * IMSI and max_chal are sent as an ASCII string,
34 * Kc/SRES/RAND/AUTN/IK/CK/RES/AUTS as hex strings.
36 * An example implementation here reads GSM authentication triplets from a
37 * text file in IMSI:Kc:SRES:RAND format, IMSI in ASCII, other fields as hex
38 * strings. This is used to simulate an HLR/AuC. As such, it is not very useful
39 * for real life authentication, but it is useful both as an example
40 * implementation and for EAP-SIM/AKA/AKA' testing.
42 * For a stronger example design, Milenage and GSM-Milenage algorithms can be
43 * used to dynamically generate authenticatipn information for EAP-AKA/AKA' and
44 * EAP-SIM, respectively, if Ki is known.
46 * SQN generation follows the not time-based Profile 2 described in
47 * 3GPP TS 33.102 Annex C.3.2. The length of IND is 5 bits by default, but this
48 * can be changed with a command line options if needed.
