Internet-of-things tampering invasion detection method in combination with abnormal monitoring

Abstract

The invention provides an internet-of-things tampering invasion detection method in combination with abnormal monitoring. Aiming at a periodic environment monitoring network, the technical problem that the real perception data is tampered by malicious node and the credibility of the data is damaged is solved. The method comprises a local abnormal monitoring step, a neighbor invasion detection step and a global invasion detection step. The space-time relativity of the data in the network is considered, and mutual supervision is performed by using the openness of a channel usable for a node and a neighbor node, so invasion detection between neighbors is realized, and the space relativity is detected by using the global invasion detection with a suspicious abnormal event node as the center; by using the result, on one hand, the monitoring and the positioning of the abnormal event are realized, and on the other hand, the invasion node close to the abnormal event can be reversely detected.

Description

technical field [0001] The invention relates to an Internet of Things tampering and intrusion detection method combined with anomaly monitoring, belonging to the technical field of Internet of Things intrusion detection. Background technique [0002] As the research and application of the Internet of Things has attracted more and more attention, the security issues of the Internet of Things have become increasingly prominent. Since the application of the Internet of Things will involve various fields such as military, people's livelihood, industry and commerce, the importance of its network security is self-evident. The intrusion against the Internet of Things mainly refers to any action that attempts to destroy the integrity, confidentiality, and accessibility of target resources, which is the main aspect of the Internet of Things security research. [0003] Traditional security defense mechanisms, such as encryption and identity authentication, are relatively passive. An...
