Abstract

The invention discloses a high-reliability computing platform, which comprises a mainboard (1), a reliable BIOS (3) and a reliable password module (2) connected through a bus. A computer is electrified, and then the reliable password module (2) is electrified at first; the mainboard (1) is kept at a reset state by controlling a power, a clock and reset signal line, meanwhile a safety control module (4) starts a BIOS integrity measuring mechanism to ensure the reliability of the BIOS and then releases the power, the clock and the reset signal; the mainboard (1) directly accesses the BIOS chip through an LPC bus and loads the reliable BIOS (3) for normal start; the reliable BIOS (3) sequentially loads a hard disk boot sector integrity measuring unit (9) and an operating system core component integrity measuring unit (10) therein to finish the software integrity measurement; and after the measurement is successful, the operating system is normally loaded and operated. The invention ensures the safety and reliability during the computer starting process.

Description

technical field [0001] The invention relates to a computing platform, in particular to a high-reliability computing platform. Background technique [0002] With the continuous development of information technology and the increasing popularity of computer networks, how to solve terminal security and network security has become an urgent problem. Trusted computing is just a research hotspot in this area. It improves the security of information systems through comprehensive measures based on hardware structure and underlying software. [0003] At present, the trusted computing platform usually integrates a security chip with cryptographic calculation and storage capabilities on the computer motherboard hardware platform, and establishes a chain of trust through integrity measurement and reporting technology to provide protection for applications running on the platform. Although such a computing platform ensures the security of computer terminals to a certain extent, it still...
