Internet of Things data sharing model based on block chain and management and control method

Abstract

The invention discloses an Internet of Things data sharing model based on a block chain and a management and control method, and realizes Internet of Things data sharing and circulation by adopting combination of an access control model based on rights and capabilities and a block chain. The scheme is realized by taking an Internet of Things data sharing platform as a carrier. The platform is realized in a front end and rear end separation mode, the front end is realized by a Vue framework, and the rear end is used for page calling of the front end in the form of RestfulAPI interface service realized based on Springboot + Mybatis. Compared with a traditional data sharing scheme, a centralized data management center is removed, data are returned to a data provider, the problem of single-point failure is avoided, and the method has the advantages of decentralized management and traceable transaction. The invention is higher in flexibility and expandability, realizes distributed access control, and is more in line with the data sharing scene of the Internet of Things. According to the invention, the authenticity of the data is ensured through the asymmetric encryption technology and the digital signature technology, and network attacks and data leakage in the transaction process are effectively avoided.

Description

technical field [0001] The present invention relates to the field of data sharing, data access control and block chain technology, and in particular to a data sharing model and control method designed based on the access control model of block chain and capabilities in the Internet of Things data sharing scenario. Background technique [0002] With the development and maturity of the Internet of Things technology, the Internet of Things has gradually developed from a concept at the beginning and penetrated into various fields, such as intelligent transportation, medical care, environmental monitoring and other industries. Hundreds of millions of IoT devices have been widely used in people's social life, and the generated IoT data has grown exponentially. The era of data has arrived. Internet of Things data is the core driving force of the Internet of Things, and there is huge value behind it, and the most important means to release the value of data is to let data flow. In ...

[0005] (2) Data management and control issues

At present, in the process of data transactions, most of the data is stored centrally on large-scale data sharing platforms, and once the data owners share their data, it is difficult to have the opportunity to participate in subsequent transactions, which can easily lead to data privacy leaks. It is also one of the reasons for the current "difficulty" of data sharing

Common management and control mechanisms such as role-based access control RBAC and attribute-based access control mechanism ABAC mostly rely too much on centralized authorization decision-making servers, which can easily cause single point of failure problems, poor flexibility and scalability, and cannot meet the Requirements in a networked environment
