Question

Explain the difference between TKIP and CCMP?

Answer 1

TKIP and CCMP are two protocoles using in wireless networks. Following are the key features and majour differences between these two protocols.

	TKIP	CCMP
1	Temporal Key Integrity Protocol	Counter Mode with Cipher Block Chaining Message Authentication Code Protocol
2	Temporary Security protocol for a wireless network using IEEE 802.11 standard	An encryption protocol for a wireless network using IEEE 802.11 standard
3	Uses a Message Integrity Code (MIC) to the MAC frame	Uses a Cipher Block Chaining Message Authentication Code (CBC) to the MAC frame
4	Uses RC4 encryption of packets for data confidentiality	Uses Advanced Encryption Standard (AES) encryption for data confidentiality
5	Uses security features like key mixing, sequence counter to protect reply attacks and Message Integrity Checks for data integrity	Uses MAC header, CCMP header for encryption purposes, Data Unit, and Message Integrity Checks for data integrity and Frame Check Sequence for data validation.
6	It is not possible to alter the transferred messages in somewhere between the conversation	The information is shared only to an authorized person on the other end
7	It is commonly using and it is with breakable security compared to CCMP	It is expensive and using with WPA2 wireless networks
8	For old devices, TKIP is a better choice	For new devices and for better data safety, CCMP is better
