Problems solved by technology
[0003] It is not difficult to understand that the security of the BIOS upgrade can be guaranteed by means of digital signatures. However, when the existing BIOS loads the signature certificate, the BIOS can only load one signature certificate at a time. In this way, when the BIOS needs to load the signature certificates of multiple items, Only the BIOS code can be modified, the operation is cumbersome, and the loading efficiency is low

Embodiment Construction
[0043] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0044] In the server, Secure Flash is a method to prevent unauthorized BIOS (Basic Input Output System, Basic Input Output System) upgrade. With Secure Flash, you can ensure that the source of the BIOS binary file is valid and prevent the BIOS file from being tampered with by others. The principle of Secure Flash is to use a set of signature certificates to generate a signed BIOS file when compiling the BIOS code, and to verify the signature of the BIOS file when refreshing. The spe...

The invention discloses a method, a system and equipment for loading a signature certificate on a BIOS (Basic Input Output System) and a computer medium. The method comprises the following steps: acquiring identification information of a target to-be-loaded item; determining a target signature certificate corresponding to the identification information of the target to-be-loaded item in a signature certificate file corresponding to the signature certificate based on a preset corresponding relation between the identification information of the to-be-loaded item and the signature certificate; wherein the signature certificate file comprises a signature certificate of each to-be-loaded item; and loading the target signature certificate. The invention provides a method, system and equipment for loading a signature certificate on a BIOS and a computer readable storage medium. The signature certificate file comprises the signature certificate of each to-be-loaded project, and the target signature certificate corresponding to the identification information of the target to-be-loaded project can be determined in the signature certificate file according to the corresponding relation betweenthe identification information of the to-be-loaded projects and the signature certificates, so that BIOS codes do not need to be modified, and the loading efficiency can be improved.
Description
technical field [0001] The present application relates to the field of server technology, and more specifically, relates to a method, system, device and computer medium for loading a signature certificate in BIOS. Background technique [0002] In the server, Secure Flash is a method to prevent unauthorized BIOS (Basic Input Output System, Basic Input Output System) upgrade. With Secure Flash, you can ensure that the source of the BIOS binary file is valid and prevent the BIOS file from being tampered with by others. The principle of Secure Flash is to use a set of signature certificates to generate a signed BIOS file when compiling the BIOS code, and to verify the signature of the BIOS file when refreshing. The specific process is: generate a set of keys, including the public key and Private key; hash the BIOS binary file to get a digest, sign the digest with the private key, get an encrypted signature file, and attach it to the BIOS Capsule file: When refreshing the BIOS, ...
