FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -WPA2 replaces RC4 and TKIP with two stronger encryption and authentication mechanisms: Advanced Encryption Standard (AES), an encryption mechanism; and. Counter Mode with Cipher Block Chaining Message Authentication Code Protocol (CCMP), an authentication mechanism.

Detailed explanation-2: -CCMP, also known as AES CCMP, is the encryption mechanism that has replaced TKIP, and it is the security standard used with WPA2 wireless networks. According to the specifications, WPA2 networks must use CCMP by default (WPA2-CCMP), although CCMP can also be used on WPA networks for improved security (WPA-CCMP).

Detailed explanation-3: -WPA2 is a security standard for wireless networks based on the Advanced Encryption Standard technology (AES). It is used with the IEEE 802.11a, 802.11b, 802.11g, 802.11n and 802.11ac WiFi standards, encrypting data in order to prevent unauthorized access.

Detailed explanation-4: -The WPA2 wireless security standard uses CCMP, which is based on the AES algorithm, to verify message authenticity and integrity.

Detailed explanation-5: -WPA2 mandates the use of a new protocol, counter mode with cipher-block chaining message authentication protocol (CCMP). CCMP uses the AES block cipher, replacing the RC4 cipher used in wired equivalent privacy (WEP) and temporal key integrity protocol (TKIP).
