Problems solved by technology

[0006] The purpose of the present invention is to propose a method for protecting sensitive data in the industrial Internet based on cloud-fog collaboration. The improvement of this method is that distributed storage is used locally, and corresponding restrictions are added to RS, which not only solves the problem of high storage pressure on local devices and local device Faults lead to the problem that data cannot be recovered, and improve the efficiency of encoding and decoding, and reduce computing costs

Embodiment Construction

[0036] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0037] figure 1 It is a schematic diagram of the fog computing architecture, including the factory terminal equipment layer, the fog computing layer and the cloud computing layer. At the bottom is the factory terminal equipment layer, the main job of this layer is to collect data and upload it to the fog server. As the middle layer of the fog computing model, the fog computing layer plays a vital role in the transmission between the cloud computing layer and the fog device. Fog nodes in the fog computing layer have certain storage capacity and computing power. The introduction of fog computing can ease the cloud computing layer and improve work efficiency. The cloud computing layer has powerful storage capacity and computing power.

Abstract

The invention discloses an industrial Internet sensitive data protection method based on cloud-mist collaboration, and the method designs an industrial sensitive data protection model. For industrial delay-sensitive data, a data protection scheme based on Adaboost and local differential privacy is designed, which protects sensitive data on the basis of ensuring data availability; for industrial non-delay-sensitive, cloud storage-based data, A data protection scheme based on AES encryption and Reed‑Solomon coding is designed. This method adopts distributed storage locally and imposes corresponding restrictions on RS, which not only solves the problem of high storage pressure on local devices and failure of local devices resulting in unrecoverable data, but also improves encoding and decoding efficiency and reduces computing costs.

Description

technical field [0001] The invention relates to a sensitive data protection method based on fog-cloud combination applied in the industrial Internet, and belongs to the technical field of industrial data protection. Background technique [0002] In the process of industrial production, a large amount of sensitive data will be generated, including the manufacturing process of the production line, cost information of products, operation data, operation information and data, marketing strategies, intellectual property rights and customer data. Once these sensitive data are leaked, it may cause a significant loss of business and even damage to a company's reputation. In the context of the Industrial Internet, ensuring that sensitive information is not leaked is a major challenge currently. [0003] In actual industrial scenarios, some sensitive data needs to be processed in real time, such as data for predictive maintenance in current smart factories. If a CNC machine tool fai...
