HLR/AuC testing gateway for hostapd EAP-SIM/AKA database/authenticator

hlr_auc_gw is an example implementation of the EAP-SIM/AKA/AKA'
database/authentication gateway interface to HLR/AuC. It could be
replaced with an implementation of SS7 gateway to GSM/UMTS
authentication center (HLR/AuC). hostapd will send SIM/AKA
authentication queries over a UNIX domain socket to and external
program, e.g., hlr_auc_gw.

hlr_auc_gw can be configured with GSM and UMTS authentication data with
text files: GSM triplet file (see hostapd.sim_db) and Milenage file (see
hlr_auc_gw.milenage_db). Milenage parameters can be used to generate
dynamic authentication data for EAP-SIM, EAP-AKA, and EAP-AKA' while the
GSM triplet data is used for a more static configuration (e.g., triplets
extracted from a SIM card).

Alternatively, hlr_auc_gw can be built with support for an SQLite
database for more dynamic operations. This is enabled by adding
"CONFIG_SQLITE=y" into hostapd/.config before building hlr_auc_gw ("make
clean; make hlr_auc_gw" in this directory).

hostapd is configured to use hlr_auc_gw with the eap_sim_db parameter in
hostapd.conf (e.g., "eap_sim_db=unix:/tmp/hlr_auc_gw.sock"). hlr_auc_gw
is configured with command line parameters:

hlr_auc_gw [-hu] [-s<socket path>] [-g<triplet file>] [-m<milenage file>] \
        [-D<DB file>] [-i<IND len in bits>]

options:
  -h = show this usage help
  -u = update SQN in Milenage file on exit
  -s<socket path> = path for UNIX domain socket
                    (default: /tmp/hlr_auc_gw.sock)
  -g<triplet file> = path for GSM authentication triplets
  -m<milenage file> = path for Milenage keys
  -D<DB file> = path to SQLite database
  -i<IND len in bits> = IND length for SQN (default: 5)

The SQLite database can be initialized with sqlite, e.g., by running
following commands in "sqlite3 /path/to/hlr_auc_gw.db":

CREATE TABLE milenage(
	imsi INTEGER PRIMARY KEY NOT NULL,
	ki CHAR(32) NOT NULL,
	opc CHAR(32) NOT NULL,
	amf CHAR(4) NOT NULL,
	sqn CHAR(12) NOT NULL
);
INSERT INTO milenage(imsi,ki,opc,amf,sqn) VALUES(
	232010000000000,
	'90dca4eda45b53cf0f12d7c9c3bc6a89',
	'cb9cccc4b9258e6dca4760379fb82581',
	'61df',
	'000000000000'
);
INSERT INTO milenage(imsi,ki,opc,amf,sqn) VALUES(
	555444333222111,
	'5122250214c33e723a5dd523fc145fc0',
	'981d464c7c52eb6e5036234984ad0bcf',
	'c3ab',
	'16f3b3f70fc1'
);

hostapd (EAP server) can also be configured to store the EAP-SIM/AKA
pseudonyms and reauth information into a SQLite database. This is
configured with the db parameter within the eap_sim_db configuration
option.

"hlr_auc_gw -D /path/to/hlr_auc_gw.db" can then be used to fetch
Milenage parameters based on IMSI from the database. The database can be
updated dynamically while hlr_auc_gw is running to add/remove/modify
entries.

Example configuration files for hostapd to operate as a RADIUS
authentication server for EAP-SIM/AKA/AKA':

hostapd.conf:

driver=none
radius_server_clients=hostapd.radius_clients
eap_server=1
eap_user_file=hostapd.eap_user
eap_sim_db=unix:/tmp/hlr_auc_gw.sock db=/tmp/eap_sim.db
eap_sim_aka_result_ind=1

hostapd.radius_clients:

0.0.0.0/0	radius

hostapd.eap_user:

"0"*	AKA
"1"*	SIM
"2"*	AKA
"3"*	SIM
"4"*	AKA
"5"*	SIM
"6"*	AKA'
"7"*	AKA'
"8"*	AKA'
