The invention provides a trusted platform module testing device which comprises a basic information testing system, a cryptographic code service testing system and a trusted service testing system. The basic information testing system is used for testing basic information of different trusted platform modules, and the basic information of the trusted platform module comprises a base attribute testing function and a function coverage rate; the cryptographic code service testing system is used for testing the basic cryptographic code function of the trusted platform module as a security chip, and the basic cryptographic code function comprises a cryptographic algorithm function, a cryptographic key certificate function and a protocol function; the trusted service testing system is used for testing trusted characteristics of the trusted platform module and the trusted characteristics comprise a trusted memory/report and testing function, a credibility degree memory report function, a terminal security service function and remote certificate function; and all the testing systems are installed on a trusted computing system in which the trusted platform module is arranged as a hardware chip. The application of the device can conduct a standard compliance test for the TPM and efficiently cover the trusted functions of the TPM to be tested.
