A network security administrator is documenting legacy and modern wireless security protocols for a corporate compliance audit. Match each wireless security standard on the left with its corresponding encryption cipher and integrity mechanism on the right.
- WEP (Wired Equivalent Privacy)RC4 stream cipher with a 24-bit Initialization Vector (IV) and CRC-32 integrity checking
- WPA (Wi-Fi Protected Access)RC4 stream cipher utilizing Temporal Key Integrity Protocol (TKIP) and Michael MIC
- WPA2 (Wi-Fi Protected Access 2)AES block cipher using Counter Mode Cipher Block Chaining Message Authentication Code Protocol (CCMP)
- WPA3-PersonalAES block cipher using Galois/Counter Mode Protocol (GCMP-128) with Simultaneous Authentication of Equals (SAE)
Answer
WEP pairs with RC4, 24-bit IV, and CRC-32; WPA pairs with RC4, TKIP, and Michael MIC; WPA2 pairs with AES-CCMP; WPA3-Personal pairs with AES-GCMP-128 and SAE.
Wireless standards evolved systematically: WEP used simple RC4 with CRC-32; WPA upgraded legacy hardware with RC4 wrapped in TKIP; WPA2 introduced mandatory AES-CCMP; and WPA3-Personal implemented AES-GCMP-128 combined with SAE.
