You are implementing wireless access at a defense contractor. Specifications say, you must implement the AES Encryption algorithm. Which encryption standard should you choose?

WPA uses TKIP (Temporal Key Integrity Protocol), which is based on RC4, not AES, and does not satisfy an AES requirement.

TKIP is an encryption protocol based on RC4 used in WPA, not an AES-based standard, and is considered cryptographically weak.

WEP (Wired Equivalent Privacy) uses the RC4 stream cipher with a static key and is deprecated due to severe cryptographic vulnerabilities.

WPA2 (IEEE 802.11i) is the only standard listed that uses AES-CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol) as its encryption algorithm. WPA2 replaced the weaker TKIP-based WPA and is required by government and defense environments that mandate AES. It provides 128-bit AES encryption, satisfying the specification described.
