WSN (Wireless Sensor Network)-oriented lightweight intrusion detection method on basis of artificial immunization and mobile agent

Abstract

The invention relates to a WSN (Wireless Sensor Network)-oriented lightweight intrusion detection method on the basis of the artificial immunization and a mobile agent, which comprises the following steps of: 1, establishing a lightweight intrusion detection model which is combined with the mobile agent, sharing information by cooperation of various role agents and completing replacement by adopting a mode of evoluting the agent by self-learning; 2, adopting an intrusion detection process of the immunity cooperation of T cells and B cells on the basis of the life cycle; and 3, realizing the self-updating capacity of an intrusion tolerance topological network of a WSN by gradually increasing novel nodes serving as renewable resources. The invention provides the WSN-oriented lightweight intrusion detection method on the basis of the artificial immunization and the mobile agent, which can be used for effectively preventing network information of the WSN from being maliciously tampered or preventing effective information from being lost due to intrusion.

Description

technical field [0001] The invention relates to an intrusion detection method applicable to a wireless sensor network (WSN). Aiming at practical problems such as information tampering and loss caused by intrusion in WSN applications, a multi-population genetic algorithm is used to realize generation of detectors and complete WSN intrusion detection. Background technique [0002] WSN has characteristics that are closely related to applications. Different applications have different security requirements. The security requirements of WSN are the fundamental basis for designing an effective security architecture. Security requirements include communication security requirements and information security requirements. Communication security is oriented to network infrastructure. Security is to ensure the normal progress of basic functions such as WSN data collection, fusion, and transmission. Communication security requirements: In an uncertain untrusted environment, the WSN syst...
