Abstract:
The present disclosure discloses a processor security checking method, system and checking device. The processor security checking method includes: acquiring recording information of data read and write operations between a processor and a peripheral device, where the data read and write operation is a data read and write operation initiated by the processor or a data read and write operation initiated by the peripheral; and determining whether the processor is secure according to the recording information of the data read and write operation and an analysis result on the data read and write operation by the checking device. The embodiments of the present disclosure may detect hardware vulnerabilities and improve the security of hardware usage.

Claim (Index 4):
The method according to  claim 3 , wherein determining whether the processor is secure according to the recording information of the data read and write operation and the analysis result on the data read and write operation by the checking device comprises:\n when the data read and write operation is an MMIO type of read operation, comparing an operation address and a data length in the recording information with an operation address and a data length obtained by analyzing the MMIO type of read operation by the checking device, and comparing an operation sequence in the recording information with an operation sequence obtained by analyzing the MMIO type of read operation by the checking device; and when the comparison results are consistent with each other, determining that the processor is secure during performing the MMIO type of read operation, otherwise determining that the processor is not secure during performing the MMIO type of read operation,
