Embodiment Construction
[0034] In the Internet of Things, complex intrusion detection algorithms are often deployed on key nodes such as gateways with sufficient resources. However, due to the openness of the Internet of Things environment and the limited resources of the underlying devices, for the underlying common Devices, etc., it is difficult to deploy complex and effective intrusion detection algorithms to detect intrusions immediately. Aiming at the problem that the underlying device resources in the Internet of Things are limited and complex intrusion detection functions cannot be realized, the present invention designs a distributed deployment method for intrusion detection functions, which divides a complex intrusion detection function into several sub-functions and deploys them separately To the detection node, thereby reducing the load required by each detection node to perform the intrusion detection function, the blockchain is used for trust management between nodes in the whole process....

The invention discloses a block chain-based distributed deployment method for intrusion detection functions, comprising the following steps: S1, selection of detection nodes; S2, distributed deployment and execution of intrusion detection functions: splitting the complete intrusion detection function into several An independent detection sub-function, and according to the distribution of detection nodes in a cluster, calculate the optimal detection data transmission path, and then deploy the sub-function on the detection nodes; S3, verify the detection node execution status, if found Malicious behaviors are packaged into blocks and broadcast. The present invention divides the complete detection function into different sub-functions and deploys them on different detection nodes, and the detection nodes cooperate to complete the detection function through the optimal data transmission path, which greatly reduces the complexity of intrusion detection for each detection node. algorithm load.
Description
technical field [0001] The present invention belongs to the security field of the Internet of Things. Specifically aiming at the limitation of computing and storage resources of Internet of Things devices, a distributed deployment method of intrusion detection function is designed, and the complete intrusion detection function is distributed and deployed on multiple detection nodes. In this way, the burden on a single detection node is reduced, and the trust management function between detection nodes is realized through blockchain technology. Background technique [0002] The Internet of Things can connect a large number of digital and physical objects (such as wireless sensor networks, smart meters, smartphones and smart appliances, etc.), while providing open access to various data generated by these devices, enabling new services for citizens and companies, but Due to the heterogeneity of devices and protocols used, data privacy and other issues, the security of the Inte...
