Abstract
The present disclosure relates to an implementation for a trusted computing system. According to the embodiments of the present disclosure, a master controller in an SSD, which is necessarily configured in the system, is used to provide all necessary security functionality of the system's RoT. The system does not need to contain any special RoT chip or module, does not need any modifications in the system design, is easy to adopt, and can be implemented by any system comprising a hard drive. All necessary security functions are completed by the master controller of the system's hard drive. Thus, not only can the cost of the security module be reduced, but more importantly, the mechanism directly protects information and resources (e.g., operating system, user programs, user data, etc.) that actually need to be protected in the system, and once the mechanism is enabled, the protection function cannot be bypassed.
