how does WPA2 AES-CCMP work?

Question

I'm looking for a generalized summary and example of how WPA2 AES-CCMP works. I'm referring to the wireless encryption.

Answer 1

AES CCMP, is the encryption mechanism that replaced TKIP, it is the standard used with WPA2 wireless networks. Per specifications, WPA2 networks must use CCMP by default (WPA2-CCMP), CCMP can also be used on WPA networks for improved security (WPA-CCMP).

Counter Mode with Cipher Block Chaining Message Authentication. CCMP provides authentication, confidentiality, and integrity checking services to any cryptographic system. Under the hood of CCMP is the AES algorithm.

AES is also a well-known, it’s a secure block cipher for encrypting data, and CCMP is a mode of using this cipher to provide both strong encryption and strong integrity protection. WPA2 required support for AES-CCMP for certification.
