SECURE POSITIONING METHOD AND APPARATUS FOR WIRELESS SENSOR NETWORK, DEVICE, AND STORAGE MEDIUM

摘要

Disclosed are a secure positioning method and apparatus for a wireless sensor network, a device, and a storage medium. The method comprises: acquiring a first receiver noise extracted when a target node receives a challenge signal, a second receiver noise extracted when an anchor point receives a response signal, and an analytic result of the response signal obtained from the anchor point; determining a target distance between the anchor point and the target node; determining an attack detection result according to the analytic result of the response signal obtained from the anchor point, the second receiver noise, the first receiver noise, and a preset detection threshold value; and if the attack detection result indicates that there is no ranging attack, positioning the target node according to the target distance, otherwise, discarding the target distance.
