Difficulty: EasyWireless Security Standards and Encryption Protocols

Which wireless security standard introduced mandatory support for the Counter Mode Cipher Block Chaining Message Authentication Code Protocol (CCMP), utilizing the Advanced Encryption Standard (AES) cipher to replace legacy TKIP encryption?

  1. WPA2Answer
  2. B
    WEP
  3. C
    WPA
  4. D
    WPA3

Answer

WPA2
WPA2 (Wi-Fi Protected Access 2), defined under IEEE 802.11i, introduced mandatory support for CCMP, which employs the 128-bit AES block cipher to deliver strong confidentiality and packet integrity.

Step-by-Step Solution

1
Identify the cryptographic mechanism described in the question prompt.
The prompt specifies the introduction of CCMP (Counter Mode Cipher Block Chaining Message Authentication Code Protocol) using AES.
Understanding which standard first mandated AES-CCMP is key to classifying 802.11 security generations.
2
Compare historical 802.11 security standards and their default encryption ciphers.
WEP used RC4 with static keys, WPA introduced TKIP over RC4, WPA2 introduced CCMP with AES, and WPA3 upgraded to GCMP-256 and SAE.
Mapping standards to ciphers isolates WPA2 as the standard that introduced CCMP.
