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'
