Problems solved by technology

However, at present, independent servers based on domestic processors such as Loongson and Phytium are basically rack-mounted servers. The main board of the server adopts E-ATX form factor and standard ATX power supply. The main board is too large in size and does not support hot swapping. and other factors cannot meet the requirements of high-density servers for computing motherboard architecture
[0004] In addition, domestic production does not mean safe and reliable, and there may still be certain hidden dangers

Embodiment Construction

[0036] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0037] An embodiment of the present invention provides a trusted boot system for safety-enhanced Loongson computing motherboards, such as figure 1 As shown, it includes the first Loongson CPU, the second Loongson CPU, the north-south bridge chip, the electronic disk and the trusted computing control circuit; The OS is stored on the electronic disk.

[0038] The first Loongson CPU is respectively connected to the second Loongson CPU and the north and south bridge chips through the HT bus. The north and south bridge chips are connected to the electronic disk through the SATA bus.

[0039]The trusted computing control circuit includes a switch module, a BIOS chip, a CPLD chip, a trusted slot mini-PCIE and a trusted module.

[0040] The switch module is connected between the second Loongson CPU and the BIOS chip through the SPI bus; the switch module is con...

Abstract

The invention discloses a trusted startup system and a trusted startup method for a security-enhanced Loongson computing mainboard. According to the method, a traditional computing mainboard startup mode is improved, a trusted computing control circuit is added, when a startup signal of a startup button or a remote startup signal of a BMC is detected, a CPU startup control signal is output to a CPU firstly, and CPU startup is interrupted; trusted measurement is carried out on the BIOS, and after measurement succeeds, a CPU reset signal is released; and then the BIOS is started, the OS kernel is measured, and after measurement succeeds, the OS is normally guided to be started, so that trusted startup is realized. And if the measurement of any link fails, the starting process is interrupted,and an alarm is given out through a buzzer and an indicator light. That is to say, a set of active defense system is established, BIOS and OS cores are measured during startup, it is ensured that Trojan horse is not modified or implanted, and the startup safety of the computing mainboard is ensured.

Description

technical field [0001] The invention relates to the technical field of trusted computing control, in particular to a trusted startup system and a trusted startup method for a safety-enhanced Loongson computing motherboard. Background technique [0002] The high-density server adopts a unique architecture design. The height of 42U can be configured with up to 76 computing motherboards. It is mainly used in large-scale data centers to serve large-scale and complex Internet applications. Compared with ordinary rack-mounted servers, it has stronger computing power and higher computing density. Taller and more flexible to expand. At present, the computing motherboards of high-density servers are designed and implemented based on Intel's X86 processors, which are still limited by foreign software and hardware products, and there are still risks of supply interruption, as well as security threats such as Trojan horses and security vulnerabilities, which seriously affect the securit...
