Method for detecting black hole attack in wireless ad hoc network

Abstract

The invention discloses a method for detecting a black hole attack in a wireless ad hoc network. The method for detecting the black hole attack is respectively carried out at each node of the network independently, and comprises the following steps of: detecting behaviors of neighbor nodes in a one-hop range of a wireless signal effective transmission distance of the node, namely collecting and analyzing the behaviors of the neighbor nodes around the node; performing analysis and statistics on the behaviors of the neighbor nodes, wherein if the statistic data of a certain neighbor node is discovered to be abnormal, the neighbor node is considered to be the black hole attacked node; and once the black hole attacked node is detected, listing the black hole attacked node in a blacklist, broadcasting the black hole attacked node, and isolating the attacked node to reduce the loss due to the black hole attack to the minimum. The invention originally provides a concrete method for detecting the black hole attacked node, and the method can reduce the attack caused loss to the minimum by taking precautionary measures immediately after the black hole attacked node is detected.

Description

technical field [0001] The invention relates to a method for detecting a black hole attack in a wireless self-organizing network, and belongs to the technical field of network security. Background technique [0002] The wireless ad hoc network is a wireless mobile multi-hop communication network, which has many different characteristics from the traditional wireless communication network: the network does not depend on any fixed infrastructure and management center, but through the cooperation between mobile nodes and Self-organization to maintain the connection between the nodes in the network, while realizing the transfer of data. Compared with the wired network, the special feature of the wireless self-organizing network is that it faces more security threats. Utilizing the essential characteristics of wireless ad hoc networks sharing wireless media, it is possible for external attackers to pretend to be legitimate nodes (Masquerade) to intercept routing information (Int...

Problems solved by technology

[0006] Although the two papers of the above-mentioned prior art provide an idea for implementing black hole attack detection, many details or specific methods for actually implementing the detection are not determined in these two papers.

That is to say, at present, most papers on the black hole detection technology of wireless ad hoc networks only provide a framework or idea, and the technical means of how to realize the detection have not yet been determined.
