Secure WLANs
Encryption Methods
WPA and WPA2 include two encryption protocols:
- Temporal Key Integrity Protocol (TKIP) – Used by WPA and provides support for legacy WLAN equipment. Makes use of WEP but encrypts the Layer 2 payload using TKIP.
- Advanced Encryption Standard (AES) – Used by WPA2 and uses the Counter Cipher Mode with Block Chaining Message Authentication Code Protocol (CCMP) that allows destination hosts to recognize if the encrypted and non-encrypted bits have been altered.
