Final answer:
WPA (Wi-Fi Protected Access) is the standard that implements the requirements of IEEE 802.11i. It offers improved security compared to WEP and fully realizes these requirements in its updated form, WPA2, using AES for data encryption.
Step-by-step explanation:
The standard developed by the Wi-Fi Alliance that implements the requirements of IEEE 802.11i is WPA (Wi-Fi Protected Access). Unlike its predecessor WEP (Wired Equivalent Privacy), which had significant security issues, WPA was designed to provide more sophisticated data encryption and user authentication. The IEEE 802.11i standard is an amendment to the original IEEE 802.11 standard on which Wi-Fi is based and specifically aims to enhance security. WPA2, which is the second generation of WPA, fully implements the requirements of IEEE 802.11i. It offers stronger data protection and network access control and uses the Advanced Encryption Standard (AES) protocol for data encryption.
