The invention provides a method for recording operation information of a processor. The method includes controlling the processor to enter a second system mode from a first system mode in response tocompletion of execution of a particular read instruction, wherein the second system mode has control over the first system mode; In the second system mode, the execution result of the specific read instruction in the first mode is read, and the instruction position of the specific read instruction is recorded to generate an event log file for processor security detection. The invention also provides a device, a system and a medium for recording the operation information of a processor. The invention can accurately and effectively acquire and record the operation information of the processor executing the specific read instruction, thereby eliminating the influence on the safety detection caused by the inconsistent generation of the operation information of the specific read instruction.
Description
technical field [0001] The present invention relates to the field of processors, and more specifically, to a method, device, system and medium for recording processor operation information. Background technique [0002] With the large-scale application of new technologies such as network informatization, information security has become an increasingly serious problem. Usually the information security we discuss is limited to network security, software security, etc. However, as recent research shows, hardware security should also receive attention. The scale of hardware design increases day by day with the improvement of hardware design level, making hardware Trojans possible: the sources of hardware IP (intellectual property rights) used in large-scale circuits represented by CPUs (processors) are currently diversified, and hardware design The complexity of the process, the division of labor in the design and manufacturing process and other factors have caused the decline ...
