Abstract

The invention discloses a method and device for detecting wormhole attacks on wireless networks and delay-tolerant networks in a three-dimensional space. The method first responds to received wormhole detection requests by nodes in the network to obtain some topological information in the adjacent areas maintained in advance. Calculate the largest independent set in the graph, and then compare the actual size of the largest independent set with the size of these largest independent sets in the predefined network to determine whether there is an illegal subgraph structure in the network; if there is an illegal subgraph structure in the network, It means that there is a wormhole attack in the network. The invention is a lightweight and distributed algorithm, which can not only efficiently identify wormhole attacks, but also facilitates the realization and deployment of wormhole attack detection devices. The present invention does not need any preconditions and assumptions, does not need to know the initial state of the network, global clock synchronization, protection nodes and special hardware devices, and has no false detection rate.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and device for detecting wormhole attacks on wireless networks and delay-tolerant networks in three-dimensional space. Background technique [0002] With the advancement of wireless communication technology and its gradual application in various fields, some new wireless communication networks distributed in three-dimensional space have gradually reflected their important application value. For example: satellite communication network, underwater acoustic sensor network. Unlike traditional ground or sea-deployed wireless networks, these wireless networks deployed in space and underwater cannot be studied by traditional methods by analyzing their abstract two-dimensional planar network topology. In addition, with the maturity of related technologies, more and more applications have been applied to delay-tolerant networks, such as land mobile networks, satellite netw...
