Problems solved by technology

First of all, most of the widely used commercial computers are based on the Intel X86 platform. The BIOS of these platforms is almost all produced by several foreign BIOS manufacturers. Due to the limitation of intellectual property rights, we cannot obtain the source code of the BIOS for system security. Enhancement; In addition, the cost of upgrading commercial computers that have been used in large quantities through source code modification is high and the feasibility is low

Abstract

The invention discloses a computer security enhancement system and method based on BIOS extension, and belongs to the field of computer security. The system is used for executing and achieving transmission of a trust chain and controlling starting of an operating system in a BIOS stage on the condition of not correcting a BIOS source code. The system is interconnected with a computer and used for conducting security enhancement on a BIOS before the operating system of the computer is started. The system is particularly implemented in the mode that an extension program loading module is interconnected with the BIOS, the trust chain is established, and the security enhancement system is operated before the operating system is started; a BIOS interaction module is interconnected with the BIOS and controlled to call BIOS basic services; an algorithm supporting module provides algorithm support; an identity authentication module verifies the user type; a hardware authentication module measures the integrity of key hardware equipment connected with the computer; a software authentication module measures key files of a nucleus of the operating system; a guiding control module is used for controlling starting equipment used by a user according to the user type.

Description

technical field [0001] The invention belongs to the technical field of computer security, and in particular relates to a computer security enhancement system based on BIOS expansion and a working method thereof. Background technique [0002] The realization of general BIOS layer security enhancement technology is completed by adding some modules in the BIOS source code, which has great limitations. First of all, most of the widely used commercial computers are based on the Intel X86 platform. The BIOS of these platforms is almost all produced by several foreign BIOS manufacturers. Due to the limitation of intellectual property rights, we cannot obtain the source code of the BIOS for system security. Enhancement; in addition, the cost of upgrading commercial computers that have been used in large quantities through source code modification is relatively high, and the feasibility is low. Contents of the invention [0003] In view of this, the present invention provides a co...
