The invention discloses an Internet of Things terminal control method and system based on a block chain. The control method comprises the following steps: a first block chain node writes first control instruction information for controlling an Internet of Things terminal into a first smart contract and broadcasts the first smart contract; the second block chain node receiving the first smart contract performs dual verification for the first smart contract and the first block chain node; and when the dual verification is passed, the second block chain node links the first smart contract, and sends first control instruction information to the Internet of Things terminal. Hash value verification and intelligent contract consensus verification are carried out on the control instruction information, so that the technical problems that the equipment instruction data are easily attacked by hackers and are not safe can be solved.
Description
technical field [0001] The present application relates to the technical field of the Internet of Things, and in particular to a control method and system for an Internet of Things terminal based on blockchain. Background technique [0002] The security authentication permission control in the existing Internet of Things system and most software systems is based on the Abac method. Using Abac alone to implement authority security control is likely to cause security problems. Ddos attacks, violent cracking of databases, etc. have a great impact on IoT systems. [0003] According to Gartner's forecast, the number of IoT devices will exceed 20 billion by 2020, and the economic impact on industry and manufacturing will reach trillions of dollars. However, the sharp increase in the number of IoT devices has brought new security risks and challenges to IoT systems. For example, in 2018, researchers at KU Leuven University in Belgium discovered that by intercepting the signal of ...
