Embodiment

[0033] In order to meet the needs of localization, the present invention realizes domestic UEFI BIOSlicence management and control based on Feiteng and Loongson localization platforms, and provides a domestic UEFI firmware license management and control method, such as figure 1 As shown, the method specifically includes the following steps:

[0034] (1) In the power-on stage, hardware information is collected, including CPU ID, memory capacity, hard disk SN, network card MAC address, etc.;

[0035] (2) Generate the unique SN of the board according to the hardware information and encryption algorithm, and record it as NewSN;

[0036] (3) Check whether there is an authorized license in the authorization code management area of ​​the BIOS SPI Flash, if it exists, go to step (4), otherwise it means the test version of BIOS, go to step (7);

[0037] (4) Read license from the authorization code management area of ​​BIOS SPI Flash;

[0038] (5) Decrypt the license information to ob...

Abstract

The invention discloses a domestic UEFI (Unified Extensible Firmware Interface) firmware license management and control method, which comprises the following steps of: in a power-on stage, collecting hardware information; generating a unique SN of the board card according to the hardware information and an encryption algorithm, and recording the unique SN as NewSN; checking whether an authorized License exists in an authorization code management area of the BIOS SPI Flash or not; reading the license from an authorization code management area of the BIOS (Basic Input Output System) SPI (Serial Peripheral Interface) Flash; decrypting the license information to obtain the SN of the authorized board card, and recording the SN as a ValidSN; comparing whether the NewSN is consistent with the VaidSN or not; and normally starting and guiding the operating system. The UEFI BIOS license management and control method is suitable for localization requirements, based on Feiteng and Loongson localization platforms, the domestic UEFI BIOS license management and control are achieved, the UEFI BIOS can be prevented from being illegally embezzled through the management and control method, and therefore the benefits of users and firmware manufacturers are guaranteed.

Description

technical field [0001] The invention relates to the technical field of domestic UEFI BIOS license management and control on a domestic platform, in particular to a domestic UEFI firmware license management and control method. Background technique [0002] Computing boards for localized platforms are currently characterized by a large number of product models and a long time for testing and verification. If it is necessary to ensure the normal testing of the user and the mass production of the product, the user must obtain the license authorization from the firmware manufacturer. [0003] At present, for the authorization control method of the domestic UEFI BIOS license of the domestic platform, there is a risk of illegal misappropriation of the UEFI BIOS, which threatens the interests of users and firmware manufacturers. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a domestic UEFI fir...
