Abstract

The present invention applies for protection of a source location privacy protection method of sector domain improved phantom routing. Aiming at the location privacy protection of source nodes in the target monitoring wireless sensor network, the present invention divides the fan-shaped area from the source node to the phantom node and protects the location privacy of the source node by the improved phantom routing in the fan-shaped domain, so that adjacent timing can be generated A certain safe distance DSecure can be maintained between the phantom nodes. Even if an attacker captures a phantom node, the location of the source node cannot be judged. The invention can also control the possibility of routing to the same phantom node for a certain period of time, and the forwarding of data packets will not be routed to the same phantom node, thus greatly improving the security of the location privacy of the source node in the wireless sensor network sex.

Description

technical field

[0001] The invention relates to the technical field of security of the Internet of Things, in particular to a location privacy protection technology of a wireless sensor network source node in its perception layer. Background technique

[0002] In recent years, the Internet of Things technology has matured and its applications have become increasingly popular. As an important part of its underlying perceptionā€”Wireless Sensor Networks (WSNs) are playing an increasingly important role. Compared with traditional networks, sensing nodes in wireless sensor networks are mostly deployed in unsupervised harsh scenarios and have the characteristics of fragile capabilities, limited resources, and weak computing power, which makes the privacy and security issues of WSNs attract much attention. WSNs privacy protection can be divided into two categories: data-oriented privacy protection and context-oriented privacy protection, and context-oriented privacy protection is fu...
