Embodiment 1

[0028] The method of realizing trusted active measurement based on domestic BMC and TPM2.0 adopts domestic BMC chip as the trusted measurement root of the system platform, and realizes the power-on sequence control of the motherboard through programmable logic in the BMC. At this time, control the BMC and TPM2.0 to be powered on first through the power supply component of the motherboard, and the CPU will not be powered on to start; when the measurement is completed, the BIOS ensures that the platform is credible, and the CPU is powered on to take over the control of the platform;

[0029] The trusted platform module TPM2.0 chip is used as the trusted root of the computing platform, specifically the trusted storage root and the trusted reporting root; the TPM2.0 chip is connected to the BMC and the south bridge chip through the LPC bus, and the LPC interface of the BMC is on the CPU Configure the main device interface before powering on, so that you can normally access the TPM2...

Abstract

The invention discloses a method for realizing trusted active measurement based on domestic BMC and TPM2.0. The method for realizing trusted active measurement adopts a domestic BMC chip as the trusted measurement root of the system platform, and uses a programmable Logically realize the power-on sequence control of the main board; use the trusted platform module TPM2.0 chip as the trusted root of the computing platform, specifically the trusted storage root and trusted reporting root; use the trusted BIOS based on the improvement of the existing BIOS, improve The trusted BIOS architecture complies with the UEFI specification. Compared with the prior art, the method for realizing trusted active measurement based on domestic BMC and TPM2.0 of the present invention is based on the combination of domestic BMC as a security management controller and TPM2.0 module as a trusted platform control unit. The functions of root of trust measurement, root of trust reporting and root of trust storage can actively measure BIOS, enable control of system equipment, and finally establish a trusted execution environment of the system platform.

Description

technical field [0001] The invention relates to the technical field of trusted measurement root, in particular to a method for realizing trusted active measurement based on domestic BMC and TPM2.0. Background technique [0002] In the existing process of building a trusted platform based on TPM / TCM technology, the static core measurement root CRTM is stored in the BIOS, and the CRTM in the BIOS and the trusted storage root RTS and the trusted reporting root RTR in the TPM / TCM Together they form the building blocks of trust. The TPM / TCM is placed on the LPC bus, and its startup is after the CPU executes the BIOS code. During the platform startup process, CRTM did not release the control right to the measured components in the next stage, so it did not reflect the idea of ​​trust transfer. [0003] Published relevant patent documents: titled "A trusted platform module and its active measurement method", which discloses "a trusted platform module and its active measurement me...
