Blockchain-based Internet of Things security detection method and system

Abstract

The invention discloses a blockchain-based Internet of Things security detection method and system. The method comprises the following steps: an Internet of Things service provider generates a systemrelease statement and broadcasts the system release statement to the Internet of Things in the form of a smart contract, wherein the smart contract comprises a cash deposit paid by the provider; an Internet of Things security detection device verifies whether the system release statement is true, and if so, records the system release statement in a blockchain; the detection device obtains and detects a corresponding Internet of Things system, and generates a first detection report if detecting a vulnerability; the provider verifies the report, and if the report is true, records the report in the blockchain and generates a second detection report, the provider verifies the authenticity and correctness of the report, and when the report is true and correct, records the report in the blockchain; the smart contract is triggered to distribute the cash deposit to the corresponding detection device; and the system is selected for installation and use by querying the detection reports. By adoption of the detection method, the integrity of vulnerability detection is improved, the security of the Internet of Things ecology is enhanced, furthermore the detection capability is high, and the fault tolerance rate is high.

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...
