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 8):
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 a P2P type of data read and write operation, comparing a data content and a data length flowing from the peripheral to the processor with a data content and a data length flowing from the processor to the destination peripheral of the P2P type of data read and write operation in the recording information; and when the comparison results are consistent with each other, determining that the processor is secure during performing the P2P type of data read and write operation, otherwise determining that the processor is not secure during performing the P2P type of data read and write operation.
