Abstract

The invention provides a method and server for integrity measurement based on BMC and TCM. The method comprises: building connection between baseboard management controller BMC and BIOS through the SPI bus, building connection between BMC and trusted cryptography module TCM through the LPC bus and storing SM3 hash algorithms and reference values in the TCM; the BMC collects key codes in the BIOS through the SPI bus; the SM3 hash algorithms stored in the TCM are called through the LPC bus for measuring the key codes to obtain measurement values; determining whether the measurement values are consistent with the reference values stored in the TCM; if the measurement values are consistent with the reference values, sending control signals to the CPU to control the power-on of the CPU and transmitting a trust chain to the key codes in the BIOS; otherwise, forbidding the start of the CPU. The technical scheme of the invention realizes trust deliver.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and server for integrity measurement based on BMC and TCM. Background technique [0002] With the application of servers in all walks of life more and more deeply, the security of servers has been widely concerned. Especially in the process of server startup, it is easy to be attacked. Therefore, it is particularly important to measure the integrity of the server to ensure the safe startup of the server. [0003] At present, the method of integrity measurement is mainly to store the static core measurement root CRTM in the BIOS, so that the CRTM is trusted by default, and the CRTM in the BIOS controls the entire startup process. During the server startup process, the CRTM does not Trust transfer cannot be achieved without releasing control to the measured component in the next stage. Contents of the invention [0004] The embodiment of the present invention provide...
