Abstract
The present disclosure provides a processor checking method, a checking device and a checking system. The method includes acquiring an access record to a memory by a processor during a running process, the access record includes a read operation information and a corresponding time information, determining whether there is a read operation information corresponding to a high access authority in the access record, and when there is a read operation information corresponding to a high access authority, determining whether the read operation information corresponding to the high access authority belongs to an unauthorized operation. According to embodiments of the present disclosure, the behavior of the processor reading data from the memory is checked and analyzed, thereby preventing the security problems caused by malicious use of unauthorized reading operation.
