Invasion detection method of radio self-organization network

Abstract

A wireless self-organized network intrusion detection method belongs to the technical field of network security, which comprises the following steps: step one, in a wireless self-organized network, the whole self-organized network is divided into a plurality of areas, and a cluster head is chosen in each area as a monitoring node in charge of the intrusion detection of the whole area, and the cluster head is used for collecting the behavior information of the nodes in the whole area; step two, the routing protocols of the wireless self-organized network are formed into a finite state machine which is then used for judging the behavior of each node in the wireless self-organized network collected by the cluster head in step one, and if the behavior of the node is not complied with the behavior of the finite state machine, the behavior of the node is regarded as an aggressive behavior, otherwise, the finite state machine enters the final state. The method of the invention is distributed cooperation intrusion detection, which requires no data training in advance and can detect intrusion behavior in real time.

Description

technical field [0001] The invention relates to an intrusion detection method in the technical field of network security, in particular to a wireless ad hoc network intrusion detection method. Background technique [0002] As a new type of mobile multi-hop wireless network, wireless ad hoc network has many different characteristics from traditional wireless networks. It does not depend on any fixed infrastructure and management center, but maintains the connection of the network and realizes the transmission of data through mutual cooperation and self-organization among mobile nodes. Compared with fixed wired networks, wireless ad hoc networks face more security threats. In order to ensure the security of wireless ad hoc networks, many security solutions have been proposed so far. But these security schemes mainly focus on key distribution and authentication, and routing security algorithms. These measures are used in wireless ad hoc networks and can play a certain role i...
