Which of the following encryption methods uses AES technology?

Dynamic WEP uses the RC4 stream cipher with dynamically rotating session keys rather than AES, and retains the fundamental cryptographic weaknesses of WEP despite the dynamic keying mechanism.

Static WEP uses the RC4 stream cipher with fixed, manually configured keys and provides no AES-based encryption, making it highly vulnerable to attacks such as IV reuse and key recovery.

TKIP was introduced as a temporary WPA upgrade over WEP but still relies on the RC4 stream cipher with per-packet key mixing rather than AES, and is now deprecated due to cryptographic weaknesses.

CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol) uses the AES-128 block cipher in counter mode for confidentiality and CBC-MAC for data integrity and authentication. It was standardized in IEEE 802.11i as the mandatory strong encryption mode for WPA2, replacing the vulnerable RC4-based WEP and TKIP protocols.
