TKIP (Temporal Key Integrity Protocol) is a deprecated data encryption protocol used in wireless networks. It was designed to provide stronger encryption than the original WEP (Wired Equivalent Privacy) protocol and was designed to be backward compatible with WEP. TKIP uses a per-packet key mixing function, an extended IV (Initialization Vector), and a re-keying mechanism.
CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol) is the encryption protocol used in 802.11i and WPA2 wireless networks. It is based on the Advanced Encryption Standard (AES) and provides strong encryption for wireless networks. CCMP uses a 128-bit block cipher for encryption, authentication and integrity. It also uses a 128-bit key and uses the CBC-MAC (Cipher Block Chaining Message Authentication Code) protocol for authentication. In addition to providing stronger encryption than TKIP, CCMP also has the advantage of being more efficient and providing better throughput.
