Compare TKIP and CCMP and indicate which is preferred today.

• A. TKIP is older encryption used with WPA; CCMP (AES-based) is more secure; CCMP is preferred.
• B. CCMP is deprecated.
• C. TKIP provides stronger security than CCMP.
• D. Both are equally secure; no difference.

Answer: (A)

The idea here is that encryption strength and integrity protection determine which wireless protocol is preferable. TKIP was created as a bridge from WEP to WPA, using RC4 for encryption and a per-packet key mix with a lightweight integrity check. That design turned out to have exploitable weaknesses in modern threat models, making it far less secure than what we need today.

CCMP, by contrast, uses AES with CCM mode, which provides both strong confidentiality and solid data integrity (authentication) for each packet. This combination is far harder to crack and much more resistant to tampering than TKIP. Because of that, CCMP (AES-based) is the standard and recommended choice for current Wi‑Fi networks.

So, CCMP is preferred today due to its stronger encryption and integrity protections. TKIP remains only for compatibility with very old devices, but it’s not the recommended security posture.
