what are the primary differences between wep wpa and wpa2?
While WEP uses simple PSK key, WPA and WPA2 combine it with other encryption methods like WPA-PSK and EAP-PSK to make the authentication process more secure. The standard which WPA and WPA2 follow for authentication is 802.1x/EAP. WPA and WPA2 use 256-bit encryption for authentication which is quite secure.
