Internet of things security detection method and system based on block chain

Abstract

Disclosed are a method and system for detecting the security of an Internet to things based on a blockchain. The method comprises: an Internet to things service provider generates a system release announcement and broadcasts same to an Internet to things in a form of a smart contract, the smart contract comprising the margin submitted by the provider; an Internet to things security detection device verifies whether the system release announcement is true; if yes, records same in the blockchain; the detection device obtains a corresponding Internet to things system, detects same, and generates a first detection report if the vulnerability is detected; the provider verifies the report; if the report is true, records same in the blockchain and generates a second detection report; the provider verifies the truthfulness and the correctness of the report; if the report is true and correct, records same in the blockchain; trigger the smart contract and distribute the margin to the corresponding detection device; select a system for installing and using by querying the detection report. The detection method improves the vulnerability detection completeness, improves the ecological security of the Internet of things, and has strong detection capability and high fault tolerance rate.

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 and system. Background technique [0002] With the development of IoT technology, the scale of IoT continues to expand. By 2020, the number of IoT devices is expected to reach 28.1 billion. However, the IoT system is extremely fragile, and its security risks will be an important factor restricting the development of IoT technology. Due to the huge number of IoT devices, distributed denial-of-service attacks caused by these devices have strong destructive power. [0003] Aiming at the security risks of the Internet of Things, the security detection technology of the Internet of Things system is also constantly developing. This type of security detection mainly has the following defects: First, the centralized security detection cannot detect all loopholes well, because the detection capabi...

AI Technical Summary

Problems solved by technology

[0006] For this reason, an object of the present invention is to propose a block chain-based Internet of Things security detection method, which solves the problem of incomplete vulnerability detection in the Internet of Things, constrains the behavior of Internet of Things service providers, and improves the vulnerability of the Internet of Things. The integrity of the detection enhances the security of the IoT ecology, and has strong detection capabilities and high fault tolerance
