Abstract
A trusted measuring method including: measuring, by a trusted platform control module, itself after being powered on; measuring, by the trusted platform control module, a high-speed encryption/decryption module when the measurement of the trusted platform control module by itself is valid; and measuring, by the trusted platform control module in combination with the high-speed encryption/decryption module, the integrity of a platform and a system when the measurement of the high-speed encryption/decryption module by the trusted platform control module is valid. The measuring process includes: calculating a measurement object by using a predetermined algorithm, comparing the calculation result with a pre-stored verification reference value, and determining that the integrity of the measurement object is not destroyed if the comparison result is consistent. The present disclosure solves the technical problems of low performance of trusted measurement, insensitiveness to attack risks, and information leakage risks in conventional techniques.
