Question

A). 128 bit and CRC
B). 64 bit and CCMP
C). 128 bit CCMP
D). 128 bit and TKIP

Answer 1

WPA2 uses AES encryption with a key size of 128 bits and CCMP encryption mode.

Step-by-step explanation:

WPA2 uses AES (Advanced Encryption Standard) for data encryption. AES is a symmetric encryption algorithm that supports key sizes of 128, 192, and 256 bits. In the case of WPA2, it uses a 128-bit key size. The encryption mode used in WPA2 is CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol), which provides data confidentiality, integrity, and authentication.

WPA2 (Wi-Fi Protected Access 2) employs the Advanced Encryption Standard (AES) for data encryption, utilizing a robust encryption algorithm. AES comes in different key lengths or strengths, including 128-bit, 192-bit, and 256-bit. In the context of WPA2, the standard specifies the use of either 128-bit or 256-bit AES encryption, depending on the configuration.

The key length directly correlates with the encryption strength; a higher number of bits generally implies a more secure encryption process. The 256-bit AES encryption, available in WPA2, provides a higher level of security compared to the 128-bit version, as it involves a larger key space, making it more resistant to brute-force attacks and enhancing the overall confidentiality and integrity of the wireless communication on the network.
