Problems solved by technology

The current false positioning coordinate points have single-point spoofing attacks, area interference attacks and other positioning hijacking attacks on the user's positioning service. By modifying the coordinate information of the real location, hijacking the coordinate information of the real location, and publishing wrong coordinate information, Causes positioning errors within a certain range, and the existence of attacks will make users receive wrong location information or achieve the purpose of interferers to implement other illegal acts

Embodiment Construction

[0058] In order to describe the present invention more clearly, the present invention will be described in detail below in conjunction with examples.

[0059] The present invention adopts the following technical solutions to realize a method for detecting area location hijacking attacks. Depend on figure 1 Shown, the present invention is divided into five main steps, and concrete steps are as follows:

[0060] Step 1: Collect N positioning data at time T in area A, and this area is marked as A T .

[0061] In the detected positioning area A, N positioning data are collected within time T, N{{(x t1 ,y t1 )|RSSI 1 , RSSI 2 ,...RSSI r ,...,RSSI R | t1}; {(x t2 ,y t2 )|RSSI 1 , RSSI 2 ,...RSSI r ,...,RSSI R | t2};...;{(x tn ,y tn )|RSSI 1 , RSSI 2 ,...RSSI r ,...,RSSI R | tn};...;{(x tN ,y tN )|RSSI 1 , RSSI 2 ,...RSSI r ,...,RSSI R | tN}(n=1,2,…,N; r=1,2,…,R)}, and mark this area A as A T .

[0062] Table 1 indicates that in area A (the side length...

Abstract

The invention provides a method for detecting region positioning hijack attacks. Through space region division, a plurality of positioning data is collected in a certain period of time in a certain positioning region; an RSSI (Received Signal Strength Indicator) relevant coordinate of the positioning data is obtained through a positioning algorithm; on the basis of the region creditworthiness threshold evaluation, an abnormal positioning region is detected; through the analysis on the timeliness and the space performance of the single-region and multi-region abnormal positioning region, the region coordinate with higher credibility is selected to be used as the finally issued coordinate. The method provided by the invention has the advantages that the region positioning hijack attack behaviors can be effectively resisted; the region detection accuracy and the positioning safety are improved; the important significance is realized on the positioning risk defense and secure positioning realization in complicated environment.

Description

technical field [0001] The invention belongs to the technical field of wireless space positioning, and in particular relates to a method for detecting and positioning hijacking based on the wireless positioning technology in a complex indoor environment. Background technique [0002] With the development of wireless communication technology and the improvement of data processing capabilities, location-based services have become one of the current Internet services. Especially in a complex environment, the demand for quickly and accurately obtaining the location information of mobile terminals or their holders, facilities and objects, and providing location services has become increasingly urgent. Communication and positioning are converging and promoting each other. The location of the mobile terminal is determined through wireless communication and related parameter measurements, and the location information can be used to support location services and optimize network man...
