Which of the following wireless standards uses a block encryption cipher rather than a stream cipher?
A. WPA2-CCMP
B. WPA
C. WEP
D. WPA2-TKIP
Correct Answer: A
Explanation/Reference:
Explanation: Counter Cipher Mode with Block Chaining Message Authentication Code Protocol or CCMP (CCM mode Protocol) is an encryption protocol designed for Wireless LAN products that implement the standards of the IEEE 802.11i amendment to the original IEEE 802.11 standard. CCMP is an enhanced data cryptographic encapsulation mechanism designed for data confidentiality and based upon the Counter Mode with CBCMAC (CCM) of the AES standard. It was created to address the vulnerabilities presented by WEP, a dated, insecure protocol.
