Which security protocol was replaced by Device Provisioning Protocol (DPP) in WPA3?

The Device Provisioning Protocol (DPP) in WPA3 was specifically designed to enhance the security and user experience during the setup of Wi-Fi devices. It replaced Wi-Fi Protected Setup (WPS), which had several vulnerabilities that could be exploited, allowing unauthorized users to gain access to secure networks.

WPS was intended to simplify the process of connecting devices to a Wi-Fi network, but its weaknesses in implementation led to serious security risks. DPP addresses these issues by providing a more secure method for device provisioning that utilizes updated authentication mechanisms and ensures that only authorized devices can connect to the network.

In this context, the other options do not pertain to the role of DPP in WPA3. Wi-Fi Protected Access (WPA) and Wireless Equivalent Privacy (WEP) refer to encryption standards, while Authentication Header (AH) is related to network security at a different layer, specifically within the context of IPsec. Therefore, the replacement of WPS with DPP in WPA3 is crucial for improving the security protocol landscape for wireless networking.
