Abstract

This invention discloses a trusted execution control method for embedded devices in the field of industrial control security technology. Based on a trusted execution environment, this method is easily implemented on embedded chips through both hardware and software methods, and can be deployed for embedded automation devices, offering convenient implementation. The method is based on a security tag classification approach, associating program files within the system with security tags and adding them to a whitelist to provide tag support for execution control. This method stores a hash value benchmark library and a whitelist module in the non-volatile storage space of the hardware root of trust, ensuring the integrity and confidentiality of the security policy. The decision-making execution control module implemented by this method distinguishes between binary programs, kernel modules, and dynamic link libraries for execution control, providing high granularity.
