What enhancement does WPA2 have over WPA?

WPA2 improves upon WPA by replacing TKIP (Temporal Key Integrity Protocol) with CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol). This change significantly enhances data protection by utilizing the more robust AES (Advanced Encryption Standard) encryption algorithm, which provides stronger security compared to TKIP. While TKIP was a step forward at the time of WPA's release, it has vulnerabilities that CCMP effectively addresses, offering a higher level of confidentiality and integrity for wireless communications.

CCMP not only strengthens encryption but also improves the overall security framework of wireless networks, ensuring that data is protected against various attacks that could exploit weaknesses found in TKIP. This makes WPA2 a preferred choice for securing wireless networks in more security-conscious environments.
