Abstract
The disclosure provides a method, a checking device and a system for determining security of a processor. The method comprises: setting an initial running state of the checking device according to initial running state information of the processor during the target running process, and taking input information of the processor during the target running process as input information of the checking device; causing the checking device to execute a task of the target running process in a manner conforming to predefined behavior to obtain at least one of output information and final running state information of the checking device, wherein the predefined behavior is a standard of hardware behavior of the processor; and determining whether the processor is secure during the target running process according to at least one of the output information and the final running state information of the checking device when the checking device completes the task of the target running process.
