Problems solved by technology

A large number of middle and low-end servers such as four-socket and two-socket servers are deployed in the market. There is not much difference between these products. As a result, the BIOS on the server produced by one manufacturer can run directly without modification on the server produced by another manufacturer. Manufacturer's intellectual property protection and corporate interests are unfavorable

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] as attached figure 1 As shown, the present invention provides an encryption authentication module, which is added in the BIOS and applied to the DXE stage of the driver execution environment, including,

[0025] The interface unit receives the BIOS startup message and authentication request after the system is powered on, and accesses the encryption chip by simulating the corresponding interface;

[0026] Encryption authentication unit realizes encryption authentication function by cooperating with encryption chip;

[0027] The comparison unit is used to compare the encryption result of the encryption authentication unit and the encryption chip, if the encryption result is the same, then the authentication is successful; otherwise, the authentication fails.

[0028] The interface unit accesses the encryption chip through GPIO simulatin...

Abstract

The invention discloses an encryption and authentication module and a BIOS firmware protection method based on the module. The method is implemented in the step that the encryption and authentication module which works in the drive execution environment (DXE) stage is added into a BIOS, wherein the encryption and authentication module is a DXE Driver, the encryption and authentication functions are achieved in the mode that 1-Wire bus timing sequence access is simulated through a GPIO, and BIOS firmware is protected. Compared with the prior art, according to the encryption and authentication module and the BIOS firmware protection method based on the module, only few devices are added in an existing hardware scheme so that the BIOS firmware can be effectively protected, the BIOS firmware is prevented from being illegally stolen, the practicality is high, the application range is wide, and popularization is easy.

Description

technical field [0001] The invention relates to the technical field of computer servers, in particular to an encryption authentication module and a BIOS firmware protection method based on the module. Background technique [0002] BIOS is an important part of the server system, reflecting the competitiveness of a server manufacturer. A large number of middle and low-end servers such as four-socket and two-socket servers are deployed in the market. There is not much difference between these products. As a result, the BIOS on the server produced by one manufacturer can run directly without modification on the server produced by another manufacturer. Manufacturers' intellectual property protection and corporate interests are unfavorable. How to simply and effectively protect BIOS firmware from being illegally stolen is an important problem to be solved. Based on this, an encryption authentication module and a method for protecting BIOS firmware based on the module are now pro...
