OVERVIEW

	Reaver performs a brute force attack against an access point's WiFi Protected Setup pin number. 
	Once the WPS pin is found, the WPA PSK can be recovered and alternately the AP's wireless settings can be 
	reconfigured.

	While Reaver does not support reconfiguring the AP, this can be accomplished with wpa_supplicant once 
	the WPS pin is known.

DESCRIPTION

	Reaver targets the external registrar functionality mandated by the WiFi Protected Setup specification.
	Access points will provide authenticated registrars with their current wireless configuration (including
	the WPA PSK), and also accept a new configuration from the registrar.

	In order to authenticate as a registrar, the registrar must prove its knowledge of the AP's 8-digit pin
	number. Registrars may authenticate themselves to an AP at any time without any user interaction. Because
	the WPS protocol is conducted over EAP, the registrar need only be associated with the AP and does not 
	need any prior knowledge of the wireless encryption or configuration.

	Reaver performs a brute force attack against the AP, attempting every possible combination in order to
	guess the AP's 8 digit pin number. Since the pin numbers are all numeric, there are 10^8 (100,000,000) 
	possible values for any given pin number. However, because the last digit of the pin is a checksum value
	which can be calculated based on the previous 7 digits, that key space is reduced to 10^7 (10,000,000) 
	possible values.

	The key space is reduced even further due to the fact that the WPS authentication protocol cuts the pin in
	half and validates each half individually. That means that there are 10^4 (10,000) possible values for the
	first half of the pin and 10^3 (1,000) possible values for the second half of the pin, with the last digit
	of the pin being a checksum.
	
	Reaver brute forces the first half of the pin and then the second half of the pin, meaning that the entire 
	key space for the WPS pin number can be exhausted in 11,000 attempts. The speed at which Reaver can test 
	pin numbers is entirely limited by the speed at which the AP can process WPS requests. Some APs are fast enough 
	that one pin can be tested every second; others are slower and only allow one pin every ten seconds. Statistically, 
	it will only take half of that time in order to guess the correct pin number.
