QUESTION: 154 Topic: 2, Volume B

What is the IV key size used in WPA2?

32
24
16
48
128

Answer(s): D

Explanation:

Every WPA key includes a 48 bit IV key, which creates 500 trillion combinations and is a stronger encryption compared to WEP. With so many combinations, the possibility of the encryption key reuse is lesser and therefore the encryption can endure hacking attacks better than WEP. WPA does not make direct use of the master encryption keys and has a message integrity checking facility.
