Secure programming system and operating method thereof
An operating method for a secure programming system is provided. Firstly, the programmer encrypts a job control package including a payload. Then, a programmable device is loaded into the programmer. If an authentication code in an authentication list complies with a device identification code of the programmable device, the programmer decrypts the encrypted job control packages so as to extract the payload. Then, the programmer calculates a first verification code according to the payload, and the programmer burns the payload into the programmable device. Then, the programmer reads the burnt payload from the programmable device and calculates a second verification code according to the burnt payload. If the first verification code and the second verification code are verified successfully, the programmable device is categorized into a first output container representing a good output container.
