Hai Shalom 4df4133917 EAP-SIM/AKA: Add support for anonymous@realm 
SIM-based EAP authentication with IMSI encryption requires a special EAP
Identity response: anonymous@realm. Then the server sends AKA-Identity
request which is answered with the encrypted IMSI. Add logic that
indicates if the special anonymous identity is used. Otherwise, this
field is used for storing the pseudonym.

Test: Connect to Carrier Wi-Fi, verify correct behavior from captures
Test: Connect to non IMSI encrypted EAP-AKA AP, verify pseudonym usage

Jouni Malinen b2b8a4cb10 EAP-SIM/AKA: Pass EAP type as argument to eap_sim_msg_finish() 
This makes it easier for static analyzers to figure out which code paths
are possible within eap_sim_msg_finish() for EAP-SIM. This will
hopefully avoid some false warnings (CID 68110, CID 68113, CID 68114).

Jouni Malinen 1e5839e06f Rename EAP server defines from EAP_* to EAP_SERVER_*

a single binary.

Jouni Malinen a9d1364c5f Merged EAP-AKA' into eap_aka.c and added it to defconfig/ChangeLog 2008-12-07 19:24:56 +02:00
Jouni Malinen 01b0569437 Added protection against EAP-AKA' -> EAP-AKA bidding down attacks

Jouni Malinen a478ef0d12 EAP-AKA': Added CK',IK' derivation 
This is based on a change request 3GPP TS 33.402 CR 0033 for version
8.1.1. The hardcoded ANID is now 'WLAN' since that is used in
3GPP TS 24.302.

Jouni Malinen 6ec4021c03 EAP-AKA': Added processing of AT_KDF and AT_KDF_INPUT attributes 
Network Name is not yet generated and validated based on 3GPP.33.402
(i.e., a hardcoded string is used in server and anything is accepted in
peer).

Jouni Malinen 04a5bad682 EAP-AKA: Validate RES Length field in AT_RES 
This change breaks interoperability with older wpa_supplicant versions
(everything up to and including wpa_supplicant 0.5.10 and 0.6.5) which
incorrectly used this field as number of bytes, not bits, in RES.
