Internet of Things equipment access control method and device based on blockchain

Abstract

The invention discloses an Internet of Things equipment access control method and device based on a blockchain, and the method comprises the steps: A), carrying out the fine-grained division of the access control authority of Internet of Things equipment, and setting a response rule of the Internet of Things equipment; B) compiling the access control authority and the response rule of the Internetof Things equipment into a smart contract, encrypting the smart contract by using an encryption algorithm, and deploying the encrypted smart contract into a blockchain through a wireless communication module contract to realize distributed storage by the blockchain; C) when the user accesses the Internet of Things resources, by a resource provider, calling the smart contract to verify whether theuser is valid or not, and if so, executing the step D) ; otherwise, executing the step E); D) enabling the valid user to be authorized and obtain the resources; and E) enabling the invalid user not to obtain the resources. The internet of things equipment access control method and device based on the blockchain have the advantages that the internet of things equipment access control method and device based on the blockchain have multiple data transmission modes, the requirements of the user for diversified data transmission modes can be met, and the data transmission safety is high.

Description

technical field [0001] The present invention relates to the field of block chains, in particular to a method and device for access control of Internet of Things devices based on block chains. Background technique [0002] Blockchain has a wide range of applications, the biggest highlight of which is smart contracts, which can be applied to access control management. But the blockchain is still in its infancy, and it has huge application scenarios in the Internet of Things. Therefore, the blockchain, which seems to be far away from us, may really subvert our financial market and even the way the entire society is constructed in many years. Because its appearance is irreversible. Using the smart contract of the blockchain, the access control is completely distributed and stored on multiple hosts. If a hacker wants to tamper with the access control authority, he needs to break through more than half of the hosts in the entire network to modify it. Such a situation is very dif...

Problems solved by technology

However, its data transmission method is relatively simple, which cannot meet the needs of users for diversified data transmission methods.

In addition, due to the lack of security measures, the security of data transmission is not high
