Abstract

The invention provides a method for measuring BIOS integrity, a baseplate management controller and a system. The method is characterized in that a standard value of a start code Boot Black of BIOS is collected and stored; when a start request is received, identification information at a start flag bit is read; whether the identification information is a first start identifier is judged, and the start code Boot Black will be measured if the information is not the first start identifier, so that a measurement value is obtained; the measurement value is compared with the stored standard value, whether the measurement value is consistent with the standard value is judged; if the measurement value is consistent with the standard value, a first reliable state identifier will be set, and the BIOS is deemed to be integral; and otherwise, a second reliable state identifier will be set, and the BIOS will be deemed to be non-integral. The scheme provided by the invention ensures safe starting of BMC.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a BIOS integrity measurement method, a baseboard management controller and a system. Background technique [0002] The Baseboard Management Controller (BMC) mainly provides remote management functions for servers through virtual keyboards, mice, interfaces, and power supplies, such as monitoring physical characteristics such as temperature, voltage, fan working status, and power supply of each component of the server. Once the BMC is maliciously attacked, it will affect the normal work of the server. Especially when malicious code is implanted during the BMC startup process, remotely managing the server through the BMC often causes security risks during the server operation. Therefore, ensuring the safe startup of BMC has become a key issue to be solved urgently. SUMMARY OF THE INVENTION [0003] The embodiment of the present invention provides a BIOS integrity measurement ...
