Description
Technical field
The utility model relates to the fields such as home brewed computer, secure and trusted, data encrypting and deciphering and authentication, specifically a kind of standard MiniPCIE module with initiatively metric function.
Background technology
Along with the speed-raising of informatization, society's change in the information age aggravates.Especially nearest 2 years, international information-security situation was more and more severeer, and information security is also more and more paid attention in countries in the world simultaneously, and has all risen to the important component part of National Security Strategy.In China side, be that the various laws and regulations of the continuous appearance of country retrain information technoloy equipment buying even if more undeniable, but the gordian technique in IT system and parts are still limited by abroad.And domesticly first can accomplish independently controlled, this is a basic condition.Domestic can not have this kind of potential safety hazard of back door, certainly not necessarily accomplishes secure and trusted completely, but still much better than uncontrollable.Autonomous controllable safety can be developed in autonomous controlled basis credible.If not independently controlled, just can not safety.
In sum, independently control computer can to increase secure and trusted module imperative.
Summary of the invention
The utility model proposes a kind of secure and trusted standard total length MiniPCIE board for home brewed computer mainboard.The technical scheme that the utility model technical solution problem adopts is: MiniPCIE interface, programmable logic device (PLD) and TCM.
The technical solution of the utility model is:
There is a standard MiniPCIE module for initiatively metric function, comprise board, board is provided with MiniPCIE interface, programmable logic device (PLD) and TCM, MiniPCIE interface and is connected TCM respectively with programmable logic device (PLD); Board is provided with a BIOS and backs up, and BIOS backup connects TCM, by the integrality of active metric check BIOS, TCM is also provided with the interface for connecting USBkey.
First board can realize measuring the active of mainboard BIOS, recovers the function of impaired BIOS data; Its secondary module by the identity of USBKey authentication of users, can also guarantee the legitimacy of user; Last module can be communicated with mainboard by PCIE bus after the system starts, the use procedure of supervisory control comuter to needing the data of encryption and decryption to operate.
Described programmable logic controller (PLC) adopts the FPGA of chip Xilinx Spartan6 series.
The signal that MiniPCIE interface connects has PCIEx1 signal, spi bus and upper electric control signal etc.
Board PCB of the present utility model adopts 8 layer circuit boards, ensure that the convenience of cabling, decreases number of vias, ensure that Electro Magnetic Compatibility.
Achieve and the active of mainboard BIOS is measured, based on the authentication of USB Key, the data transmission of PCIE bus and data encryption feature.The integrality of MiniPCIE module tolerance BIOS after mainboard powers on, and by USB Key identifying user identity, both confirming just can start up system successfully.After system starts, board is communicated with mainboard by PCIE bus interface, completes the function of monitoring to system upper layer application and data encryption.
Accompanying drawing explanation
Accompanying drawing 1 is structured flowchart of the present utility model.
Embodiment
Below in conjunction with Fig. 1, this patent is described in detail.
As Fig. 1, programmable logic controller (PLC) adopts the FPGA of chip Xilinx Spartan6 series, and home brewed computer mainboard is connected by MiniPCIE interface with satisfying crypto module, the PCIE data path after this interface can provide system to start between mainboard and module.Special TCM in module is read by spi bus and repairs bios program, by USBKey authentication of users information.
After home brewed computer mainboard powers on, CPU controls at reset mode by the utility model and mainboard cooperation always, wait for module to BIOS initiatively measure successfully and USBKey authentication pass through just discharge cpu reset signal afterwards, if unsuccessful, first recover.After system for the treatment of starts, module is communicated with mainboard by PCIEx1 bus, real-time supervisory control comuter operation and encryption and decryption data.
Except the technical characteristic described in instructions, be the known technology of those skilled in the art.
