Abstract

The invention provides a BMC firmware security verification method and system. The method comprises the following steps: preprocessing a mirror image file of the BMC firmware to obtain a first digestvalue and a signature value; The image file and the signature value are calculated respectively, and the operation results are compared with the first digest value to verify the integrity and legitimacy of the BMC firmware. The system comprises a BMC firmware and a BMC firmware signature unit, which is used for preprocessing the mirror file of the BMC firmware to obtain a first digest value and asignature value; The BMC firmware verification unit calculates the image file and the signature value respectively, compares the operation result with the first digest value respectively, and verifiesthe integrity and legitimacy of the BMC firmware. At the same time, the invention verifies the integrity and legitimacy of the BMC firmware, and ensures the security of the BMC firmware to be updated.

Description

technical field [0001] The invention relates to the field of server firmware, in particular to a security verification method and system for BMC firmware. Background technique [0002] BMC (Baseboard Management Controller) is the baseboard management controller of the server. It has been widely used in the field of servers. It uses virtual keyboards, interfaces, mice, and power supplies to provide remote management functions for servers. Users can remotely monitor the physical characteristics of the server through the network port of the BMC, such as the temperature, voltage, fan working status, power supply, and chassis intrusion of each component. [0003] In recent years, attacks against servers have gradually shifted from upper-layer software to lower-layer firmware, such as BMC. It makes it possible for third-party malicious actors to implant malicious codes, viruses, and Trojan horses into the server firmware. If the BMC is attacked by a threat, it will cause the serv...
