Jouni Malinen	d5e2b2d274	WPS UFD: Use pre-configured DH keys only with OOB ... The old behavior of generating new DH keys can be maintained for non-OOB cases and only OOB (in this case, with UFD) will use the pre-configured DH keys to allow the public key hash to be checked.	2009-02-26 22:09:35 +02:00
Masashi Honma	46bdb83acd	WPS: Add UFD support (USBA out-of-band mechanism) ... This patch is only for the following use case: - Enrollee = wpa_supplicant - Registrar = hostapd internal Registrar Following UFD methods can be used: - Enrollee PIN with UFD - Registrar PIN with UFD - unencrypted credential with UFD Encrypted credentials are not supported. Enrollee side operation: wpa_cli -i ath0 wps_oob <device type> <mount point> <oob method> oob method = pin-e/pin-r/cred wpa_cli -i ath0 wps_oob ufd /mnt/ pin-r Registrar side operation: ./hostapd_cli -i ath0 wps_oob <device type> <mount point> <oob method> oob method = pin-e/pin-r/cred hostapd_cli -i ath0 wps_oob ufd /mnt/ cred	2009-02-26 21:57:38 +02:00
Jouni Malinen	b3ddab2122	WPS: Pad DH Public Key and Shared Key to 192 octets ... WPS spec is not very specific on the presentation used for the DH values. The Public Key attribute is described to be 192 octets long, so that could be interpreted to imply that other places use fixed length presentation for the DH keys. Change the DH derivation to use fixed length bufferd by zero padding them from beginning if needed. This can resolve infrequent (about 1/256 chance for both Public Key and Shared Key being shorter) interop issues.	2009-01-22 19:32:58 +02:00
Jouni Malinen	7d7b8e960a	WPS: Split wps_common.c into parts ... To make it easier to find various functions, attribute functions were split into wps_attr_{build,parse,process}.c.	2008-11-29 13:16:26 +02:00
