Which WiFi encryption standard is based on 802.11i and uses AES with CCMP to provide enhanced confidentiality, integrity, and authentication?

The encryption standard that is based on 802.11i and utilizes AES with CCMP to deliver improved confidentiality, integrity, and authentication is WPA2. This standard was developed to replace the less secure protocol, WPA, and is designed to provide a higher level of security for wireless networks.

WPA2 specifically mandates the use of CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol), which is an encryption protocol that operates under the AES (Advanced Encryption Standard). This combination offers robust security features by ensuring that the data transmitted over the network is encrypted, providing confidentiality, while also verifying the authenticity of the information to maintain integrity.

In contrast, other options either represent older or less secure protocols, such as WEP, which is now considered obsolete due to its numerous vulnerabilities, and WPA, which was an interim solution that does not provide as strong security as WPA2. PSK refers to Pre-Shared Key, which is a method used for entering a password in a wireless network, but it does not represent a specific encryption standard on its own. Therefore, WPA2 is the standard that aligns with the requirements mentioned in the question.
