Authorization method suitable for industrial environment

Abstract

The invention relates to the technical field of industrial environments, and discloses an authorization method suitable for an industrial environment, a scanning device for confirming an industrial environment authorization method different from a manufacturer, information of a to-be-authorized scanning device is obtained, an asymmetric algorithm is utilized, an authorized device can confirm the identity of an authorization device and obtain an authorization file, the number of authorizable times of a fuse bit on authorization scanning equipment is set, equipment information is encrypted through an encryption algorithm agreed with the authorization equipment on the basis of a pre-acquired first key to obtain an equipment information ciphertext, and the first key and the equipment information ciphertext are sent to the authorization device so as to enable the authorization device to be based on the first key. The authorization method suitable for the industrial environment has the advantages that a user authorizes each system and equipment, is responsible for operation, avoids vulnerabilities, can set the number of burnt authorization files, and limits authorization management of the equipment, further a protection mechanism is improved, and potential safety hazards and the like are avoided.

Description

technical field [0001] The invention relates to the technical field of industrial environment, in particular to an authorization method applicable to the industrial environment. Background technique [0002] Factory production will produce waste, and the shape of waste produced by different factories is very different. Environmental quality is an important part of the investment environment and quality of life. The prevention and control of environmental pollution largely restricts the production cost and operation of factories. Efficiency, the relationship between pollution control costs per unit output and waste emissions can be expressed by an exponential curve. For certain purposes, equipment manufacturers will set up a protection mechanism for equipment. Equipment can only be used after authorization. Common authorization The method is: obtain the authorization by burning the authorization file to the authorized device, especially the device using STM8, STM32 and other ...
