Problems solved by technology

However, most of the current RSS-based WLAN security detection methods can only locate a single attacker. When multiple attackers use the same identity to cooperate with each other to launch a spoofing attack, none of these methods can determine the physical location of the attacker.
3. RSS is a physical property related to wireless signals.

Embodiment Construction

[0065] The invention provides an RSS-based wireless spoofing attack positioning method, including:

[0066] S1. Establishing a location fingerprint database corresponding to the WLAN environment;

[0067] S2. Using the beacon to monitor the wireless data packets in the WLAN in real time, and then extract and obtain the RSS data stream of each node;

[0068] S3. Use the K-central point algorithm to select multiple K values, and cluster the RSS data streams of each node in turn according to each K value to obtain the corresponding clustering results, and finally obtain multiple clustering results for each node Class results; in the K-center point algorithm, the initial value of K is 2, and the value of K is increased by 1 each time it is clustered until it reaches the preset maximum value;

[0069] S4. After evaluating multiple clustering results obtained by each node, an optimal clustering result corresponding to each node is obtained;

[0070] S5. After sequentially obtainin...

Abstract

The invention discloses an RSS-based wireless spoofing attack positioning method. The method comprises steps: a position fingerprint database corresponding to a WLAN (Wireless Local Area Network) environment is built; a beacon is adopted to monitor wireless data packets in the WLAN in real time, and an RSS data flow for each node is further acquired; a K-medoid algorithm is used for selecting multiple K values, and according to a corresponding clustering result after each K value carries out clustering on the RSS data flow for each node sequentially, multiple clustering results for each node can be acquired finally; after the acquired multiple clustering results for each node are evaluated, the optimal clustering result corresponding to each node is acquired; and after a representative object of multiple clusters in the optimal clustering result is acquired sequentially, the position fingerprint database is combined to calculate and acquire the position coordinates of an attacker, and a positioning result is outputted. One or more attackers can be positioned, the positioning accuracy is high, and the method of the invention can be widely applied to the wireless information safety field.
