Problems solved by technology

[0008] However, the empirical research on the existing nonlinear phase error work shows that the phase error fingerprints generally drift to a certain extent in the time dimension, resulting in overlapping fingerprints between different devices, resulting in serious underreporting and affecting the accuracy of the detection results. accuracy

The method includes the steps of establishing an AP fingerprint database based on the phase error drift range; The steps of legality detection; the steps of traceability and identification of the detected pseudo APs; the method of the present invention can realize the accurate identification of the pseudo APs of the whole model, and solve the limitations of the detection model of the traditional RAP detection scheme and the low detection rate. problems, to achieve the purpose of maintaining network security and protecting user privacy.

Description

Full-model pseudo-AP detection method and detection device based on phase error drift range technical field The invention belongs to the technical field of communication security, particularly a kind of full-model pseudo-scale based on phase error drift range AP detection method and detection device. Background technique [0002] With the widespread use of wireless local area networks (WLAN), its security issues have become particularly prominent and important. RAP is IEEE A long-standing security threat in 802.11 wireless local area networks. A RAP attack is when an attacker exploits the 802.11 protocol suite. Weaknesses in the body, imitating legitimate access point information, establishing fraudulent access points, deceiving wireless users to connect, so as to achieve The purpose of monitoring, manipulating, and tampering with victim communications. RAP has a wide range of attacks, easy to implement, difficult to detect, and serious consequences. This type of ...
