Which Wi‑Fi security protocol is commonly associated with AES for encryption?

Explanation:
AES, the Advanced Encryption Standard, is a strong symmetric cipher used to protect data on modern Wi‑Fi networks. The Wi‑Fi security protocol that uses AES for encryption is WPA2, which employs AES in CCMP mode to provide both confidentiality and data integrity for wireless traffic. WEP is outdated and relies on RC4 with weak initialization vectors; WPA was a transitional step that used TKIP, but AES became standard with WPA2. TLS and PGP serve different roles—TLS secures communications over a network transport, not the wireless link itself, and PGP encrypts email and files.
