A home user wishes to secure the wireless network using strong encryption, so they decide to use AES. Which of the following would be used as the encryption method?

The correct answer is B. CCMP. AES (Advanced Encryption Standard) in wireless networking is implemented through CCMP (Counter Mode with CBC-MAC Protocol). CCMP is the encryption protocol used in WPA2 and provides both data confidentiality (via AES in counter mode) and data integrity/authentication (via…

Explanation

AES (Advanced Encryption Standard) in wireless networking is implemented through CCMP (Counter Mode with CBC-MAC Protocol). CCMP is the encryption protocol used in WPA2 and provides both data confidentiality (via AES in counter mode) and data integrity/authentication (via CBC-MAC). TKIP uses the older RC4 cipher and is associated with the original WPA standard. WEP also uses RC4 and is considered broken. CHAP is a point-to-point authentication protocol, not a wireless encryption method. When a wireless standard specifies AES encryption, CCMP is the underlying protocol implementing it.
