Which of the following WAP security features offers the STRONGEST encryption?

WPA uses TKIP (Temporal Key Integrity Protocol) with RC4 as its underlying cipher, which is an improvement over WEP but considered weaker and more vulnerable than WPA2's AES-CCMP.

WPA2 uses AES (Advanced Encryption Standard) with CCMP (Counter Mode with CBC-MAC Protocol), which is a strong, NIST-approved cryptographic algorithm mandated by the IEEE 802.11i standard. This replaced the weaker TKIP used in WPA and the fundamentally broken RC4-based WEP algorithm.

WEP (Wired Equivalent Privacy) uses RC4 with static or poorly managed keys and has well-documented cryptographic vulnerabilities that allow it to be cracked in minutes.

Hiding the SSID is a network obfuscation technique that prevents casual discovery of the network name but provides absolutely no data encryption or authentication security.
