Difficulty: EasyWireless Security Standards and Encryption Protocols

Match each wireless security standard to its primary encryption algorithm or authentication mechanism.

  • WEPRC4 stream cipher with static 24-bit Initialization Vectors (IV)
  • WPATKIP (Temporal Key Integrity Protocol)
  • WPA2CCMP / AES (Counter Mode Block Cipher Chaining Message Authentication Code Protocol)
  • WPA3SAE (Simultaneous Authentication of Equals)

Answer

WEP pairs with RC4 with static IVs; WPA pairs with TKIP; WPA2 pairs with CCMP/AES; WPA3 pairs with SAE.
The security protocols align directly with their cryptographic evolution: WEP relies on RC4 with static IVs, WPA introduces TKIP, WPA2 enforces CCMP with AES, and WPA3 Personal implements SAE key exchange.

Step-by-Step Solution

1
Identify the cryptographic foundation of legacy WEP.
WEP uses the RC4 stream cipher combined with static 24-bit Initialization Vectors.
WEP is the original 802.11 security protocol known for static IV collision vulnerabilities.
2
Identify the interim mechanism introduced with first-generation WPA.
WPA introduced TKIP to provide per-packet key mixing over RC4.
TKIP allowed firmware-only upgrades for existing WEP hardware while improving security.
3
Identify the mandatory cipher suite introduced in WPA2.
WPA2 mandates CCMP, which uses AES for data confidentiality and integrity.
IEEE 802.11i required AES-CCMP to replace vulnerable RC4-based protocols.
4
Identify the key establishment protocol used in WPA3 Personal.
WPA3 Personal replaces PSK with SAE (Simultaneous Authentication of Equals).
SAE provides Dragonfly key exchange to protect against offline dictionary attacks.
