Difficulty: EasyWireless Security Protocols (WPA, WPA2, WPA3)

Which encryption cipher suite does the WPA2 wireless security standard use by default to ensure data confidentiality and integrity for wireless network traffic?

  1. AES-CCMPAnswer
  2. B
    TKIP
  3. C
    RC4
  4. D
    DES-CBC

Answer

AES-CCMP is the default encryption cipher suite used by WPA2.
WPA2 requires the use of Advanced Encryption Standard (AES) operating in Counter Mode with Cipher Block Chaining Message Authentication Code Protocol (CCMP). This combination guarantees strong data confidentiality and frame authenticity.

Step-by-Step Solution

1
Identify the primary encryption mechanism required by the WPA2 standard.
WPA2 implements the full IEEE 802.11i standard, which specifies AES with CCMP as the mandatory cipher suite.
AES-CCMP provides strong 128-bit encryption along with Message Integrity Check (MIC) to ensure data privacy and authenticity.
