The invention provides a trusted computing module and a trusted starting method applying the module. The system comprises: a reset control unit, a trusted storage unit, a trusted measurement unit, a trusted recovery unit. The reset control unit is connected with a reset control circuit of a computing platform, and controls the computing platform to enter a reset state. The trusted storage unit stores the backup data information started by the computing platform; The trusted measurement unit measures the information to be measured initiated by the computing platform and generates a measurementresult. When the measurement result is trustworthy, the trusted measurement unit controls the trusted start of the computing platform. When the measurement result is not trusted, the trusted recoveryunit replaces the information to be measured with the corresponding backup data information in the trusted storage unit. The reset state of the computing platform is controlled, and the trusted recovery of the computing platform is realized. The defense capability of the computing platform is improved, and the safe start of the computing platform is ensured.
