Embodiment Construction

[0013] see figure 1 , the system adopts dual redundant / dual active / high availability cluster mode, adopts CPCI architecture, and adopts 1+1 redundant mode for power supply.

[0014] see figure 2 , in each set of trusted computer subsystems, a medium-sized FPGA is extended between the TCM and the motherboard BIOS and CPU to realize bus interface conversion and bus switch control between the TCM, BIOS and processor systems. details as follows:

[0015] 1) TCM is connected to FPGA through SPI, and after FPGA is converted to LPC, it is connected to BIOS and CPU to realize active measurement.

[0016] 2) TCM self-defined bus interface PSRAM is converted to PCI through FPGA. The CPU can access and call the trusted service of the TCM through the PCI bus.

[0017] 3) The CPU reset signal is connected to the FPGA and is controlled by the TCM. When the power is turned on, the TCM starts first and puts the CPU in a reset state.

[0018] 4) The BIOS is connected to the FPGA through...

Abstract

The invention provides a trusted redundant fault-tolerant computer system which aims at satisfying the requirement for high safety and high reliability of systems in safety control fields. The trusted redundant fault-tolerant computer system is capable of blocking the operation of illegal programs of malicious codes, viruses and the like, protecting the system and core applications from being destroyed, protecting important information from being revealed, stolen, tampered and ruined, and shielding faults by means of a failure switching function to enable the system to work normally when faults of the system occur. The trusted redundant fault-tolerant computer system is based on a trusted cryptography module (TCM) safety chip, and a dual-computer redundant hot standby method and a compact peripheral component interconnect (CPCI) bus framework are used. Two trusted computer subsystems are configured in a computer case, each of the trusted computer subsystems is composed of a trusted computer main module (including a TCM and a flash disk), a power source module, a flash disk expansion module and an interface expansion module, and the failure switching between the two subsystems is achieved through a heartbeat server and a failure switching module.

Description

technical field [0001] The invention relates to a highly credible and highly reliable computer system, which belongs to the technical field of safety control. Background technique [0002] With the rapid development of computer technology, a large number of computers are used as system control equipment in the fields of aviation, aerospace, military and industrial control, as well as some key areas with "7×24" uninterrupted operation requirements. With the increasing scale and complexity of engineering systems, once untrustworthy and unreliable problems occur in such systems, it may cause huge losses of personnel and property. For example, in 2011, Iran's nuclear safety accidents continued to occur, and the U.S. drone ground control system was invaded by malicious code. [0003] Safety, reliability, durability and reliability are the requirements of users for computer control systems. Due to the introduction of trusted computing technology, the reliability requirements of ...
