WPA-PSK
WPA-PSK (WPA Pre-Shared Key) is special mode of WPA for small business or home users. A shared key, or
password, is configured in the wireless access point (WAP) and any wireless laptop or desktop devices. WPA-PSK
generates a unique key for each session between a wireless client and the associated WAP for more advanced
security.
