1 Automatic regression and interoperability testing of wpa_supplicant's 2 IEEE 802.1X/EAPOL authentication 3 4 Test program: 5 - Linked some parts of IEEE 802.1X Authenticator implementation from 6 hostapd (RADIUS client and RADIUS processing, EAP<->RADIUS 7 encapsulation/decapsulation) into wpa_supplicant. 8 - Replaced wpa_supplicant.c and wpa.c with test code that trigger 9 IEEE 802.1X authentication automatically without need for wireless 10 client card or AP. 11 - For EAP methods that generate keying material, the key derived by the 12 Supplicant is verified to match with the one received by the (now 13 integrated) Authenticator. 14 15 The full automated test suite can now be run in couple of seconds, but 16 I'm more than willing to add new RADIUS authentication servers to make 17 this take a bit more time.. ;-) As an extra bonus, this can also be 18 seen as automatic regression/interoperability testing for the RADIUS 19 server, too. 20 21 In order for me to be able to use a new authentication server, the 22 server need to be available from Internet (at least from one static IP 23 address) and I will need to get suitable user name/password pairs, 24 certificates, and private keys for testing use. Other alternative 25 would be to get an evaluation version of the server so that I can 26 install it on my own test setup. If you are interested in providing 27 either server access or evaluation version, please contact me 28 (j (a] w1.fi). 29 30 31 Test matrix 32 33 +) tested successfully 34 F) failed 35 -) server did not support 36 ?) not tested 37 38 Cisco ACS ----------------------------------------------------------. 39 hostapd --------------------------------------------------------. | 40 Cisco Aironet 1200 AP (local RADIUS server) ----------------. | | 41 Periodik Labs Elektron ---------------------------------. | | | 42 Lucent NavisRadius ---------------------------------. | | | | 43 Interlink RAD-Series ---------------------------. | | | | | 44 Radiator -----------------------------------. | | | | | | 45 Meetinghouse Aegis ---------------------. | | | | | | | 46 Funk Steel-Belted ------------------. | | | | | | | | 47 Funk Odyssey -------------------. | | | | | | | | | 48 Microsoft IAS --------------. | | | | | | | | | | 49 FreeRADIUS -------------. | | | | | | | | | | | 50 | | | | | | | | | | | | 51 52 EAP-MD5 + - - + + + + + - - + + 53 EAP-GTC + - - ?
