Difficulty: EasyWireless Security Standards and Encryption Protocols

Match each wireless security standard on the left with its primary encryption algorithm or cipher suite on the right.

  • WEPRC4 stream cipher
  • WPA2CCMP (AES)
  • WPA3GCMP-256 (AES)

Answer

WEP corresponds to the RC4 stream cipher; WPA2 corresponds to CCMP (AES); WPA3 corresponds to GCMP-256 (AES).
Each wireless security standard aligns with a specific cryptographic protocol: legacy WEP uses the RC4 stream cipher, WPA2 standardizes CCMP based on AES, and WPA3 introduces stronger GCMP-256 AES encryption.

Step-by-Step Solution

1
Identify the cipher used by WEP.
WEP uses RC4.
WEP was designed around the RC4 stream cipher, which is now considered deprecated and vulnerable.
2
Identify the encryption suite mandated by WPA2.
WPA2 uses CCMP (AES).
The IEEE 802.11i standard defining WPA2 requires CCMP with AES for encryption and integrity.
3
Identify the enhanced encryption suite defined for WPA3.
WPA3 uses GCMP-256 (AES).
WPA3 upgrades wireless encryption to Galois/Counter Mode Protocol using 256-bit AES.
