The CCST Cybersecurity Study Guide specifies that AES (Advanced Encryption Standard) is the encryption method used in modern WiFi security protocols like WPA2 and WPA3.
"WPA2 and WPA3 use the Advanced Encryption Standard (AES) for securing wireless traffic. AES provides strong symmetric encryption, replacing outdated methods like WEP and TKIP." (CCST Cybersecurity, Basic Network Security Concepts, Wireless Security section, Cisco Networking Academy) A (DES) is outdated and insecure.
B (Triple DES) is older and slower, rarely used in WiFi.
C is correct: AES is the industry standard for WiFi security.
D (RSA) is asymmetric encryption used in key exchange, not bulk WiFi encryption.
