IOT equipment behavior credibility supervision method based on block chain

Abstract

The invention provides an IOT equipment behavior credibility supervision method based on a block chain, which is based on the block chain and the Internet of Things technology and is applied to the field of the Internet of Things. Aiming at the problem that a large amount of equipment lacks an effective security protection mechanism and is prone to attack to make untrusted behaviors in the Internet of Things industry at present, an IOT equipment supervision and management network architecture based on a block chain is designed, Internet of Things nodes are supervised by using a block chain technology, the nodes making untrusted behaviors are found and processed, and the security of the Internet of Things equipment is effectively improved. The method specifically comprises the steps that a block chain is deployed on an Internet of Things platform, a verification node on the chain generates a comprehensive reputation value for a common node according to data generated when the common node works by using algorithms such as deep learning and a neural network, and the comprehensive reputation value of each node is judged by using an artificial intelligence algorithm; and untrusted behaviors generated by the nodes whose reputation value is judged to be lower than the set reputation value threshold are reported, and support is provided for subsequent corresponding management and control operations.

Description

technical field [0001] The invention relates to the technical fields of block chain and Internet of Things, and is a scheme for supervising the behavior of Internet of Things network nodes by using block chain technology. This solution generates reputation values ​​for all IoT network nodes and records them on the blockchain, reports the untrustworthy behavior of nodes that are judged to be lower than the set reputation value threshold, and provides support for subsequent corresponding management and control operations. Background technique [0002] With the advent of the era of big data, the rapid development of the Internet of Things industry has enabled the large-scale application of Internet of Things technology in many industries. Due to the large number of IoT devices, fragile computing and storage capabilities, and open environments, a large number of IoT devices are deployed in harsh environments that are unmonitored due to factors such as cost and management, and la...

These IoT devices are vulnerable to hijacking

Hijacked IoT devices are often illegally invoked and controlled by malicious software, resulting in abnormal behaviors such as denial of service, information interception, and injection of a large number of redundant data packets on network nodes, which in turn enables criminals to achieve the purpose of destroying network devices and tampering with data
