Wi-Fi Protected Access 2 (WPA2), as described in Wi-Fi Protected Access 2 (WPA2) Overview,
the May 2005 The Cable Guy article, is a product certification
available through the Wi-Fi Alliance that certifies wireless equipment
as being compatible with the IEEE 802.11i standard.
802.11i standard formally replaces Wired Equivalent Privacy (WEP) in
the original IEEE 802.11 standard with a specific mode of the Advanced
Encryption Standard (AES) known as the Counter Mode Cipher Block
Chaining-Message Authentication Code (CBC-MAC) protocol (CCMP). CCMP
provides both data confidentiality (encryption) and data integrity.
This article describes the details of the WPA2 implementation of AES
CCMP for encryption, decryption, and data integrity validation of
802.11 wireless frames.
Great Article in the August edition of the The Cable Guy.
