AI Technical Summary
In existing technologies, terminal devices cannot distinguish between maintenance events and genuine tampering events when detecting tampering events, resulting in reduced detection accuracy.
By detecting whether authorization information for the device to enter maintenance status has been received, the current signature code and verification code of the security module are obtained, and a second verification code is generated using a pre-agreed key. If the verification codes match, the device is determined to have been tampered with based on the current signature code and the signature code of the production stage.
This improves the accuracy of tampering detection, avoids mistaking maintenance status for tampering status, and thus ensures the security of equipment data.
