Embodiment Construction

[0028] refer to Figure 1 to Figure 6 The invention realizes the credible startup of the service boards in the VPX equipment, so that the service boards in the VPX equipment run in a mutually trusted environment.

[0029] The types of boards in the VPX device include main control boards, switching boards, and service boards, such as figure 1 shown. The main control board is integrated with a trusted module. As the physical root of trust, the trusted module is the basis for realizing the trusted startup of VPX equipment. The main control board uses the trusted module to realize the trusted Metrics to complete the Trusted Boot process. The switching board provides the switching channel of the control plane and the data plane for the main control board and the service board, and the switching channel of the data plane is controlled on and off according to the result of the trusted start of the board. The business boards include Intel i7 business boards of X86 architecture and ...

Abstract

The invention discloses a credible starting method suitable for a service board in a VPX device, and relates to a credible starting implementation method for service boards in a network device of a VPX product standard. The method includes: performing credible authentication on a main control board during starting of a service board of the VPX device; downloading files such as an operation system kernel program, a file system, an application program of the service board from the main control board to complete starting; and controlling on-off of a data plane channel of the service board according to the credible authentication result of the service board. The method achieves credible starting of two different kinds of framework service boards including an Intel i7 service board and a Loongson service board, solves the problem of credible starting of the service board in the VPX device, and allows the service board in the VPX device to operate in a credible environment.

Description

technical field [0001] The invention relates to VPX technology, in particular to a trusted start-up method for service boards in VPX equipment. Background technique [0002] With the rapid development of computer technology, the traditional VMEbus and CompactPCI computer standards can no longer meet the application requirements of various industries, especially high-speed rail, medical, communication, and aerospace industries. The volume puts forward higher demands, and it is required to ensure stable work in harsh environments. [0003] In order to meet the above demands, the United States organized 28 large companies to jointly formulate and launch the VPX product standard. The VPX product standard not only supports high-speed serial switching architectures, such as Rapid IO, PCIE and Gigabit Ethernet, but also clarifies the main reinforcement indicators including vibration, shock, temperature, electromagnetic compatibility, moisture resistance, and dust resistance. At t...
