Which protocol uses TKIP encryption?

• A. WEP
• B. WPA
• C. WPA2
• D. WPA3

Answer: (B)

TKIP was created to fix the vulnerabilities of WEP without forcing new hardware, and it is the encryption method associated with the original WPA protocol. WPA uses TKIP to provide per-packet key mixing and a stronger integrity check (Michael) along with an extended IV, which significantly improves security over WEP. As a result, the protocol that uses TKIP encryption is WPA. WPA2 and WPA3 move beyond TKIP to AES-based CCMP (and newer schemes in WPA3), so they don’t rely on TKIP. WEP, by contrast, uses the RC4 cipher with weak IV handling, not TKIP.
