Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] The architecture of the present invention is mainly composed of three parts: the client, the blockchain network, and the device. The architecture diagram is as follows figure 1 shown, including the following steps:

[0032] S1: Establish the three parts of the strategy architecture client, blockchain network, and device. And set up the application SDK on the client side, and set up the edge device gateway on the device side, so that the three parts of the network can communicate with each other;

[0033] S2: Build an Ethereum main chain on the blockchain network, and confirm the identity of the client and device in the blockchain network through the application SDK and edge device gateway, thereby performing identity verification;

[0034] S3: Multiple sidechains are built according to network needs, and the data of each side...

Abstract

The invention discloses a block chain access control model strategy based on main and side chain cooperation, which comprises the following steps: S1, establishing a model strategy architecture part, and configuring gateways connected with each part; S2, configuring an Ethereum main chain on the block chain network to perform identity verification; S3, establishing a side chain, and establishing a connection with the Ethereum main chain through a Plasma contract; S4, according to the access control model, designing a related smart contract and deploying the smart contract on a side chain; and S5, enabling the user to upload the resource content and the access rule to obtain a complete access control model strategy. The invention provides an industrial Internet of Things access control model strategy based on main-side chain cooperation aiming at the problem that access control in an industrial Internet of Things environment needs to solve a single-point fault and efficient transmission at the same time, and an access control model is optimized aiming at a platform. The data transmission speed and the throughput of the block chain platform are obviously improved, and the related cost of access control in the industrial Internet of Things can be effectively reduced.

Description

technical field [0001] The invention relates to the field of access control, in particular to a blockchain access control model strategy based on cooperation between main and side chains. Background technique [0002] During the rapid development of the Industrial Internet of Things, the Internet of Things also bears the massive data from the industry. However, for traditional industrial IoT systems that rely heavily on centralized servers, fatal shortcomings such as data privacy protection and reliable transmission are seriously affecting the development of industrial IoT. Access control is a data protection technology that can ensure that data can only be accessed by authorized users. However, the current access control mostly uses a centralized server to complete authorization decisions. This design is prone to single-point failure problems. lower. At the same time, traditional access control is easily intercepted and tampered by a third party during data transmission. ...
