Final answer:
Key reinstallation attacks exploit design weaknesses in the WPA2 network security protocol.
Step-by-step explanation:
Key reinstallation attacks exploit design weaknesses in the WPA2 network security protocol. WPA2, which stands for Wi-Fi Protected Access 2, is a widely used protocol for securing wireless networks. In a key reinstallation attack, an attacker tricks a client device into reinstalling an already in-use encryption key, which can lead to unauthorized access and information leakage.
