How to ensure worry-free mass production of core data security?

When the product is officially converted to mass production and burning, are you worried about whether the batch burning process can really guarantee the security of core sensitive data? Is it plagued by anyone who has intentionally stolen the fortress, and whether there are reliable and effective protection measures? Today we come to share a mechanism of encryption engineering that allows you to realize mass production without worry.
Encryption engineering is a mechanism that is designed and implemented for the secure burning and mass production of ICs. Through the use of complex encryption algorithms to encrypt sensitive data such as project configuration and burning files, even if people get garbled characters from the encryption project, the security of the data itself can be achieved; in addition, a secure and reliable authorization system is required to ensure any Unauthorized burners cannot open encryption projects to illegally steal production, assuring that encryption projects can only be produced on specified burners.
Taking the P800 series as an example, let's look at how the encryption project is set up. The following steps are divided into functions for explanation.
* Step: Create and configure a burning project according to the normal process;
The second step: configure à project configuration à project information, in this page check the "encryption project" item, and set the password. When this step is completed, the original burning data file has been encrypted to generate a new encrypted file (stored in the project directory). At this time, the original data file can be deleted from the burner to avoid leakage of the original data. Follow-up If you need to modify the project configuration of the encryption project, you must enter the correct password.

The third step: configure à project configuration à project option-operation, in this page can configure the general operable items, such as this example only open the "mass production" operation, production line employees can only perform "mass production" operation, thus Avoid performing other actions that lead to accidents.

Step 4: Configure à Project Configuration à Project Options - Configuration. On this page, you can configure general configurable items. For example, all the configuration items are removed in this example. This way, employees in the production line will not be able to configure and modify the burning project. Randomly modifying the configuration results in an accident.

Step 5: Encryption works can be limited to burning on a machine. By default, only the production project's local machine can open the encryption project. If the encryption project is created and used on different burners, the manufacturer must additionally generate an authorization file for the specified machine. The default name is new.lic, and the deployment is performed. When you reach the target machine, overwrite new.lic with "project name.lic".
