9.3 Wi-Fi Protected Setup (WPS)

Most modern Access Points support Wi-Fi Protected Setup method, typically using the push button method. From the user’s perspective WPS is a simple mechanism to make a device connect securely to an AP without remembering passwords or passphrases. WPS uses asymmetric cryptography to form a temporary secure link which is then used to transfer a passphrase (and other information) from the AP to the new station. After the transfer, secure connections are made as for normal static PSK configuration.
