Abstract
A method for processing an asynchronous event by a checking device and a checking device are provided, the method including: obtaining an instruction position where a checked processor executes an asynchronous event during a target running process; and executing the asynchronous event at the instruction position during executing a task of the target running process in a manner conforming to predefined behavior, wherein the predefined behavior is a hardware behavior standard of the processor. Obtaining the instruction position and executing the asynchronous event at the instruction position may cause the checking device and the checked processor to process the same asynchronous event at the same instruction position. In this way, during performing security checking on a processor, the method and the device according to the embodiments of the present disclosure may be used to eliminate the influence of the uncertainty factor of the asynchronous event.
