AES-CCMP

(AES-Counter Mode CBC-MAC Protocol) The encryption algorithm used in the 802.11i security protocol. It uses the AES block cipher, but restricts the key length to 128 bits. AES-CCMP incorporates two sophisticated cryptographic techniques (counter mode and CBC-MAC) and adapts them to Ethernet frames to provide a robust security protocol between the mobile client and the access point.

AES itself is a very strong cipher, but counter mode makes it difficult for an eavesdropper to spot patterns, and the CBC-MAC message integrity method ensures that messages have not been tampered with. See 802.11i, AES, counter mode and CBC-MAC.

* WLAN Authentication and Encryption - Starting in FY 2007, new acquisitions of wireless technology must be 802.11i compliant and WPA2 Enterprise certified, implement 802.1X access control with EAP-TLS mutual authentication, and a configuration that ensures the exclusive use of FIPS 140-2 minimum overall Level 1 validated AES-CCMP communications.
The technology also includes secure authentication using WPA2 (AES-CCMP) and a DHCP server to provide unique addresses for each authenticated client.
