A clone detection method with low storage requirements in wireless sensor networks

Abstract

The invention discloses a clone detection method with low storage requirements in a wireless sensor network, which consists of two parts: (1) Creation of witness nodes: the witness information of each node is stored in multiple discrete circular arcs along the circumferential direction On the node of the path; the angle between any arc segment and the center of the circle should not be repeated as much as possible, and the position of the arc path from the center of the network is random. In this way, the attacker cannot determine the location of the witness node and is difficult to launch an attack, which has strong security. (2) When a node performs clone detection, multiple detection routes are initiated along the radial direction of the network, and the distance between any two detection routes is less than the length of the witness node arc, so as to ensure that the detection route will definitely meet the witness node, thus get tested. The innovation of the method of the present invention lies in that the circular arc paths and detection routes of the witness nodes are evenly distributed in the whole network so as to fully utilize the storage space and remaining energy of the regional nodes of the remote base station.

Description

technical field [0001] The invention belongs to the field of wireless network data security, and in particular relates to a clone detection method with low storage requirement, how to detect whether nodes in the network are cloned. Background technique [0002] A wireless sensor network is a wireless network composed of a large number of sensor nodes that communicate with each other through multi-hop wireless links and in a self-organizing and multi-hop manner.

Problems solved by technology

[0003] The cloning problem is a kind of problem: the attacker obtains all the information of these nodes by breaking through some nodes in the network, and then clones these information into multiple copies and copies them to multiple sensor nodes.

[0004] From the above, we can see that the most critical issues of clone detection are: (1) How to select the witness node

(3) The clone detection route should not be able to be calculated by the attacker in advance, otherwise, the attacker can intercept the detection route in advance and make the detection invalid

But the deficiency of the central protocol research is: if the adversary captures the base station information or interferes with the communication of the base station, then the central detection fails

In this way, what the node obtains after passing the mapping function is only the area where the witness node is located, but the specific witness nodes are not known, so it is relatively difficult for an attacker to break through all the witness nodes in this area
