Description
Technical Field
The invention relates to the technical field of laser cutting software security, in particular to a software authorization method and system of laser cutting equipment.
Background
In the laser cutting device software industry, software security has been a non-negligible problem. Software developers may use various techniques and methods for authorization protection of software for the purpose of maintaining legal rights. The user can use the software only after having been authorized.
The software authorization of the laser cutting device is embodied in such a way that a user can use the software after obtaining the use license. At present, the common mode of software authorization is as follows: registration codes, authorization certificates, etc. The software authorization process based on the activation code may be described as a simple verification of the acquired activation code by the activation end to determine whether the user is allowed to activate. Once the activation code is checked, corresponding software can be used, and a permanent activation mode is adopted in most cases, so that a time-limited activation mode cannot be realized. In case the activation code is compromised, the security thereof is also reduced as the activation code is compromised. The authorization mode of the authorization certificate has higher confidentiality. But the activation mode based on the authorization certificate needs to import the authorization certificate into the software needing authorization, and then the software to be activated performs authorization operation. While ensuring security, its authorization process is relatively complex.
If the laser cutting system adopts the activation code for authorization, once the activation code is leaked, the laser cutting system can be used, and users with long use time needs cannot meet the needs based on the activation code authorization mode. And if the authorization is directly performed by using the authorization certificate mode, the process is too complex. And unlike the way that general system software can be used only by direct installation, laser cutting system software requires both software and hardware to operate.
