![]() ![]() With a purpose of preventing attackers from obtaining relevant information by the device identification method above, we design a novel defense mechanism based on stream cipher. Here, a detailed analysis on the effectiveness of 802.11ac fields is given and a novel device identification method based on deep learning whose average f1-score exceeds 99% is presented. We propose device identification based on 802.11ac probe request frames. However, implicit identifiers are used by attackers to identify user’s device, which can cause the leakage of user’s privacy. Therefore MAC address randomization is proposed to protect the privacy of devices in a Wi-Fi network. ![]() The MAC address represents the unique identifier of the device, and is easily obtained by an attacker. Wi-Fi network has an open nature so that it needs to face greater security risks compared to wired network. ![]()
