A design method and control operation method of a trusted computer based on a power platform

Abstract

The invention provides a Power platform-based trusted computer design method and control and operation method. A trusted computer comprises a power source (PowerOn), a trusted platform control module (TPCM), a base-board management controller module (BMC), a central processing unit module (CPU), base-board management controller firmware (BMC firmware), and central processing unit firmware. When the system power source (PowerOn) is electrified, the trusted platform control module (TPCM) starts automatically and controls other module power sources of the system. By performing trust measurement on modules, measurement for the base-board management controller module (BMC) and the system PNOR and control to a power source of the base-board management controller module (BMC) and the system power source are achieved, so that problems about computer terminal and network security are solved from the bottom layer, the reliability is improved and workload of software is reduced.

Description

Technical field [0001] The invention relates to the technical field of trusted computer design, in particular to a trusted computer design method and a control operation method based on a Power platform. Background technique [0002] The 21st century is the era of information and the era of rapid development of information security technology. On the one hand, the rapid development of the information technology industry has brought huge benefits and convenience to people. On the other hand, we are also facing the severe test of various incidents in which information security has been compromised. The high stacking of firewalls and layered intrusion detection are only passive defenses. People gradually realize that solving the hidden dangers of computer terminals can eliminate the bottleneck of information security. Therefore, the information security of the source computer must be ensured. And this must take comprehensive measures from the microcomputer's chip, hardware struct...

AI Technical Summary

Problems solved by technology

[0004] At present, there are relatively few application literatures on the trusted platform control module TPCM in computer design. For example, a trusted computing platform disclosed in a Chinese patent with the publication number CN101901319A and a trust chain transfer verification method are only authorized by the trusted platform control module TPCM. The CPU performs chain measurement on the trusted computing platform and can defend against TOUTOC attacks, but does not consider the trusted platform control module TPCM, baseboard management controller module BMC, central processing unit module CPU, baseboard management controller firmware ( BMC firmware) and the central processing unit CPU firmware trust measurement problem, there is a network security problem of passive one-sided defense, which in turn restricts the development of information security
