A Location and Path Concealment Protection Method Based on IPv6 Technology

Abstract

The invention provides a hidden position and path protection method based on an IPv6 (Internet Protocol Version 6). The method comprises the following steps: changing the IPv6 address of a user periodically, encrypting communication between the user and a subnet gateway, making the user send an inquiry request to a server via the subnet gateway, and inquiring a road path ranging from a selected point in a subnet from a destination by using the subnet as an inquiry unit; returning information of the road path ranging from the selected point to the destination back to the subnet gateway by using the server; and inquiring a path ranging from the user to the selected point inside the subnet by using the subnet gateway to obtain information of the path ranging from a user position to a user destination. The method is suitable for privacy protection in a wireless sensor network environment, and the time complexity and space complexity of calculation are lowered.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a location and path concealment protection method based on IPv6 technology. Background technique [0002] Location service is the use of sensor equipment to obtain the location information of user terminals, and through the communication network provided by the service provider, it is provided to the user himself or others and the communication system with the support of the electronic map platform to realize location services, location navigation, query, etc. Value-added services related to spatial location, such as processing, scene recognition, and event inspection. In recent years, with the rapid development of wireless sensor technology, mobile network and satellite communication technology, location-based service technology has been more and more widely used. [0003] Users disclose their locations to remote servers in order to obtain location se...

(2) The service provider does not protect the user's information effectively

[0005] Existing methods mostly introduce a trusted third party or middleware between the user and the server to hide the user's location, but with the improvement of query quality requirements and privacy protection requirements, the query range and iteration times continue to increase. As the computational complexity increases, the cost of middleware query conversion and position conversion and maintenance of false positions will become very expensive, and it is difficult to apply in the sensor environment; the method of path privacy protection for moving objects usually stores a large number of fake positions. path to confuse the attacker, which requires a lot of storage space and is not suitable for sensor nodes
