[0023] In order to more clearly describe the technical content of the present invention, further description is given below in conjunction with specific embodiments.

[0024] The method for implementing encryption and decryption processing for the denture processing program in the numerical control system of the present invention comprises the following steps:

[0025] (1) Import the files and equipment to be processed, and set the preparation information;

[0026] (2) Setting the machine model configuration name on the processing equipment so that the processing equipment communicates with the central control program;

[0027] (3) The device number, model configuration and expiration date are used to generate a string of encrypted information using the Advanced Encryption Standard algorithm;

[0028] (4) embedding the encrypted information into a processing program and encrypting it together with the processing program;

[0029] (5) The processing equipment loads the encrypted processing program and decrypts the encrypted information in the processing program;

[0030] (6) Compare and check the machine's equipment number and model configuration. If normal, continue processing; otherwise, report an error.

[0031] As a preferred embodiment of the present invention, the step (6) is specifically as follows:

[0032] (6.1) Determine whether the machine's device number and model configuration are consistent and within the validity period. If so, the loading is successful and processing begins. After processing is completed, the next file will be loaded; otherwise, a corresponding error message will be given and the processing equipment will terminate loading and processing.

[0033] As a preferred embodiment of the present invention, the preparation information set in step (1) includes the correspondence between the processing equipment and the processing files as well as the effective date and the expiration date.

[0034] As a preferred implementation of the present invention, the step (4) generates a program file with a suffix in the format of "original suffix name + en" after encryption.

[0035] The device for implementing encryption and decryption processing for the denture processing program in the numerical control system of the present invention, wherein the device comprises:

[0036] a processor configured to execute computer executable instructions;

[0037] The memory stores one or more computer executable instructions. When the computer executable instructions are executed by the processor, the steps of the method for encrypting and decrypting the denture processing program in the numerical control system are implemented.

[0038] The processor in the numerical control system of the present invention is used to implement encryption and decryption processing for the denture processing program, wherein the processor is configured to execute computer executable instructions. When the computer executable instructions are executed by the processor, the various steps of the method for implementing encryption and decryption processing for the denture processing program in the above-mentioned numerical control system are implemented.

[0039] The computer-readable storage medium of the present invention stores a computer program thereon, and the computer program can be executed by a processor to implement the various steps of the method for encrypting and decrypting a denture processing program in the above-mentioned numerical control system.

[0040] In a specific embodiment of the present invention, a method for encrypting a program is provided, an encryption and decryption method for binding a processing program with information such as equipment, machine type configuration, and validity period is disclosed, and a method for automatically encrypting and decrypting and loading a program in an automatic cycle processing system is disclosed; so as to realize one-to-one binding of processing programs, equipment, and machine type configurations, provide a validity period limit for the use of processing programs, and prevent processing errors caused by program leakage or incorrect use. At the same time, a method for automatically encrypting a program is provided, which eliminates the manual processing of the encryption step of the processing program and realizes the automatic cycle of processing.

[0041] The present invention uses the advanced encryption standard algorithm to generate a string of encrypted information through the device number, model configuration and usage period, and then embeds this string of encrypted information into the processing program, encrypts it together with the processing program, and generates a program file with a suffix in the format of "original suffix name + en". When the denture program loads the program file, it decrypts the encrypted information in the processing program, and compares the decrypted device number and model configuration with the device number and model configuration of the current machine. If the two data are consistent and within the validity period, the program can be loaded normally for processing. If it is found after comparison that at least one of the two data is inconsistent or not within the validity period, the program cannot be loaded, and the denture program gives a corresponding prompt message.

[0042] In addition, the present invention realizes automatic embedding of encrypted information through a central control program, sets the correspondence between the device number, machine model configuration, effective time, expiration time and processing program on the central control program, and then automatically generates an encrypted program file, and then loads the program from the central control program into the CNC processing system to realize automatic cycle processing.

[0043] The specific implementation of the present invention is as follows:

[0044] Import the files and equipment to be processed on the central control program, set the corresponding relationship between the processing equipment and the processing files, as well as the effective date and expiration date, set the model configuration name of the machine on the processing equipment, communicate between the central control program and the processing equipment, and click Start Processing on the central control program. The equipment number, model configuration and validity period information are encrypted and embedded into the processing program and encrypted together to generate a program file with the suffix "original suffix name + en". The encrypted processing program is then loaded onto the corresponding equipment. The processing equipment checks the processing program before starting processing. If it is consistent with the equipment number and model configuration of this machine and is within the validity period, the loading is successful and processing starts. After processing is completed, the next file is loaded, and the cycle continues. If there is an inconsistency with the equipment number and model configuration of this machine or it is not within the validity period, an error is reported to the operator to terminate the loading and processing of this equipment program.
