You are trying to select a particular wireless encryption algorithm. You are concerned that it implements as much of the wireless 802.11i standard as possible. Which encryption algorithm should you…

WEP (Wired Equivalent Privacy) predates 802.11i entirely and uses RC4 with well-documented weaknesses, making it non-compliant with the 802.11i standard.

WPA implements only a subset of 802.11i as an interim measure, relying on TKIP rather than the mandatory AES-CCMP encryption required by the complete standard.

WEP2 is not a recognized or ratified wireless encryption protocol or standard.

WPA2 implements the complete IEEE 802.11i standard, requiring AES-CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol) for data confidentiality. Unlike WPA, which was a transitional partial implementation using TKIP, WPA2 satisfies all mandatory requirements of the 802.11i specification and is considered the full ratification of that standard.
