Method for selecting IDA (intrusion detection agent) start strategies of wireless sensor network

Abstract

The invention discloses a method for selecting IDA (intrusion detection agent) start strategies of a wireless sensor network. Aiming at the wireless sensor network adopting a cluster structure and in view of the detection rate and false alarm rate of IDA, data transmission reliability of the wireless sensor network, the success attack rate of attacker and other factors, the method calculates the "attack" probability of a malicious node and the "start" probability of the IDA by virtue of a game model between a "signaling game" establishing node and the IDA so that the benefit of the IDA in the strategy selection between " start" and " not start" is maximized, so as to provide the optimal strategy for determining when to start the IDA. The method not only ensures the safe wireless sensor network, but also enables the IDA not to be in a "start" state all the time, thereby saving energy comsumption used for running the IDA and prolonging the lifetime of the wireless sensor network.

Description

technical field [0001] The invention relates to the field of intrusion detection in network security technology, in particular to a method for selecting a starting strategy of a wireless sensor network intrusion detection agent. Background technique [0002] As a task-oriented network, wireless sensor network not only needs to transmit data, but also needs to collect and integrate data, and coordinate tasks to be controlled. How to ensure the confidentiality of task execution, the reliability of data generation, the efficiency of data fusion, and the security of data transmission has become a comprehensive consideration of wireless sensor network security issues. It can be said that security issues are a very key factor restricting the development of wireless sensor networks. [0003] At present, the mechanisms to ensure network security mainly include two major mechanisms: prevention and detection. The prevention mechanism mainly provides data confidentiality, integrity a...

Problems solved by technology

However, compared with the existing network, the sensor nodes have great shortcomings in terms of computing power, storage capacity, and communication bandwidth, and running the intrusion detection agent itself needs to consume more computing and energy resources. Therefore, the existing methods make wireless The life cycle of the sensor network is greatly shortened, and the intrusion detection system cannot be widely used to ensure the security of the wireless sensor network
