Message Integrity Check (MIC) and IEEE 802.1x. WPA uses Advanced Encryption
Standard (AES) in the Counter mode with Cipher block chaining Message
authentication code Protocol (CCMP) to offer stronger encryption than TKIP. WPA
applies IEEE 802.1x and Extensible Authentication Protocol (EAP) to authenticate
wireless clients using an external RADIUS database. The WPA protocol affords
users with vastly stronger security than the WEP protocol. It comes in two
different varieties: WPA and WPA2. Always try to use WPA2 as it implements the
full version of the security standard while WPA does not.
Pre-Shared Key (PSK)
A pre-shared key is a password shared between the server and the client that
unlocks the algorithm used to encrypt the data traffic between them. Without the
proper password, the client and the server cannot communicate.
Extensible Authentication Protocol (EAP)
An enhanced security framework designed to improve an existing security
protocol, such as WPA-PSK or WPA2-PSK.
