Summary: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 reliabi
