Embodiment 1

[0044] A trusted computing unit based on domestic TCM, including a mechanical structure layer, a platform hardware layer, a firmware layer, an operating system layer, and a trusted software layer;

[0045] The mechanical structure layer includes the chassis, cooling system, and power supply; the firmware layer includes Kunlun firmware; the operating system layer includes the operating system; the platform hardware layer includes the backplane, the computing unit module, and the trusted password module; the trusted software layer includes the trusted application module, Trusted computing support module; such as figure 1 shown;

[0046] The trusted computing support module is a bridge for the trusted application module to access the trusted cryptographic module. The trusted application module uses the security functions provided by the trusted cryptographic module by calling the interface of the trusted software base and the trusted software service. The security functions inclu...

Embodiment 2

[0057] A kind of operation method of the trusted computing unit based on domestic TCM described in embodiment 1, comprises the steps as follows:

[0058] (1) After the system is turned on, measure the integrity of the BIOS of the whole machine;

[0059] (2) Authenticate users;

[0060] (3) Measure the integrity of optical drives, hard disks, graphics card hardware and key kernel files;

[0061] (4) After the integrity measurement is completed, the system loads, enters the login interface, and invokes the USBKey and TCM chip to complete the identity authentication together;
