AbstractDisclosed is a measurement mechanism-based credible PLC starting method, comprising the following steps: a step of performing own firmware verification initialization; a step of reading firmware information for calculating a PLC; a step of performing one-by-one verification and storage; and a step of performing operating starting stage verification. According to the method of the present invention, an industrial-grade chip having a credible function is used as a hardware calculation core, a PLC extends a Flash bus thereof to be loaded by the hardware of the method of the present invention, the hardware of the method of the present invention identifies necessary starting information, the necessary starting file of a PLC system is subjected to integrity verification by an integrity verification method, and the PLC system is ensured to be in a credible state after being started. The present invention can build built a safe and credible industrial control system operating environment while ensuring the accuracy and practicability of terminal equipment safety.
