Internet of Things access control system and method based on block chain

Abstract

The invention discloses an Internet of Things access control system and method based on a block chain, and the method comprises the steps: S1, carrying out the initialization, building a certificate,building a HyperledgerFabric network, and completing the initialization of a block chain network; s2, chain code installation: after a HyperledgerFabric network is established, designing chain codes,and then enabling an administrator to install all the chain codes on a common node by executing a command on a Hyperledger client; s3, strategy making: enabling the user and the administrator to complete making of an access control strategy together and store the access control strategy in the blockchain system, and then enabling the administrator to upload the made access strategy to the blockchain system; s4, uploading the resource URLs, reporting the resource URLs to an intelligent gateway by the equipment, and then uploading the resource URLs to a block chain system and the like by the intelligent gateway; according to the invention, the security and throughput of the Internet of Things control system are improved, and the data consistency and the like can be ensured.

Description

technical field [0001] The present invention relates to the technical field of distributed systems, and more specifically, to a blockchain-based Internet of Things access control system and method. Background technique [0002] With the development of the Internet and computer hardware, more and more devices are connected through wireless networks, and the scale of the Internet of Things is also increasing. We live in a world where everything is connected. [0003] The Internet of Things is a distributed network consisting of a large number of sensors and gateways. In the Internet of Things, devices are always interacting with their surroundings, generating different types of data resources, such as images, audio, video, digital signals, etc. All systems and applications in the Internet of Things can efficiently share resources and information by accessing the Internet. However, due to the distributed deployment of IoT devices and their large number and scale, it is a huge...

Problems solved by technology

However, these methods are centralized designs, which have the disadvantages of single point of failure, difficult expansion, low reliability, and low throughput.

In fact, IoT devices may belong to different organizations or users, may be mobile and have limited performance, which makes it difficult for centralized access control to meet the requirements of access control in IoT environments
