Internet of Things security detection method, device and system based on block chain, and medium

Abstract

The embodiment of the invention provides an Internet of Things security detection method, device and system based on a block chain and a medium, and the method comprises the steps: carrying out the abnormality monitoring of the Internet of Things according to the monitoring information of each Internet of Things device in the Internet of Things, and obtaining the corresponding abnormality information if the abnormality of the Internet of Things is determined according to the abnormality monitoring result; generating detection information according to the abnormal information, and determining a detection block in the blockchain according to the detection information, wherein the detection block comprises at least one block in the blockchain; storing the detection information, and broadcasting storage address information in the block chain; receiving a detection result of the detection block, wherein the detection block obtains corresponding detection information according to the storage address information, and detects the detection information based on the smart contract in the block chain to obtain a detection result. According to the embodiment of the invention, decentralized security detection is realized by using the block chain, and the network security of the Internet of Things can be ensured.

Description

technical field [0001] The present invention relates to the technical field of Internet of Things security, in particular to a block chain-based Internet of Things security detection method, monitoring equipment, a block chain-based Internet of Things security detection system, and a computer-readable storage medium. Background technique [0002] In recent years, with the emergence and development of the Internet of Things, more and more IoT devices have appeared on the market. However, most of the existing IoT energy devices focus on function realization, and security issues are generally ignored in system design. [0003] As the application of the Internet of Things becomes more and more extensive and the scale becomes larger and larger, multi-level network security threats and security risks are also increasing. The threats and losses posed by network viruses and Dos / DDos attacks are increasing. Network attacks Behaviors are developing towards distributed, large-scale, an...

[0002]In recent years, with the emergence and development of the Internet of Things, more and more IoT devices have appeared on the market. However, most of the existing IoT energy devices focus on Functional implementation, security issues are generally ignored in system design

[0003] With the application of the Internet of Things becoming more and more extensive and the scale becoming larger and larger, multi-level network security threats and security risks are also increasing. Network viruses, Dos / Threats and losses posed by DDos attacks are increasing, and network attacks are developing toward distribution, scale, and complexity. Existing network security protection technologies are no longer able to meet the security needs of the Internet of Things
