Problems solved by technology

[0003] At present, the mini PCIE encryption card is a encryption card that supports the mini PCI-E interface. Although the mini PCI-E interface can support the USB communication protocol and the PCI-E communication protocol at the same time, when the encryption card communicates with the host, it only supports One of the PCI-E protocol and the USB protocol, when the host is replaced, it will cause a mismatch with the protocol supported by the host and limit the use of the encryption card; moreover, the common mini PCIE encryption card only uses one when communicating with the host Physical interface for data encryption processing, such as PCI-E interface or USB interface; that is, at the same time, there is only one channel between the mini PCIE password card and the host for encryption processing

Embodiment 1

[0051] Such as figure 1 As shown, the first aspect of the present invention proposes a kind of mini PCIE password card, and described mini PCIE password card comprises FPGA chip, security chip and first physical noise source chip, the second physical noise source chip, and is used for communicating with external host computer Connected PCI-E interface and USB interface;

[0052] The FPGA chip communicates with an external host through the PCI-E interface, and communicates with the security chip through an SPI interface to form a first communication channel; the first communication channel is used to implement: the The FPGA chip obtains the data assembled by the external host through the PCI-E interface, performs summary calculation and symmetric cryptographic operation processing, and returns the data processed by the FPGA chip to the external host through the PCI-E interface for analysis and processing; The received data is processed by key management and asymmetric cryptogr...

Embodiment 2

[0062] On the basis of the mini PCIE password card in Embodiment 1, the present invention also proposes a data communication system.

[0063] In this embodiment, the data communication system includes an external host and the above-mentioned mini PCIE password card; the external host supports the selection of the first communication channel corresponding to the PCI-E interface and the corresponding USB interface through a self-defined device driver. The second communication channel communicates with the mini PCIE cipher card simultaneously; or, selects to communicate with the mini PCIE cipher card through the first communication channel corresponding to the PCI-E interface or the second communication channel corresponding to the USB interface; The above-mentioned self-defined device drivers include USB device drivers and PCIE device drivers.

[0064] Specifically, when the external host uses a self-defined USB device driver to communicate with the security chip through the USB...

Embodiment 3

[0076] On the basis of the data communication system in embodiment 2, the present invention also proposes a kind of communication method of mini PCIE password card, as figure 2 shown.

[0077] The data communication method includes: a configuration process and a working process;

[0078] Configuration process:

[0079] The FPGA chip of the mini PCIE password card in the configuration embodiment 1 is communicated with the external host through the PCI-E interface, and is communicated with the safety chip through the SPI interface to establish the first communication channel;

[0080] The security chip of the mini PCIE password card among the configuration embodiment 1 communicates with the external host through the USB interface, to set up the second communication channel;

[0081] Configure the first physical noise source chip and the second physical noise source chip to communicate with the FPGA chip to generate random numbers and send them to the FPGA chip;

[0082] work...

Abstract

The present invention proposes a kind of mini PCIE cipher card, data communication system and method, described method is: select the first communication channel corresponding to the PCI-E interface and the second communication channel corresponding to the USB interface, carry out simultaneously with mini PCIE cipher card Communication: the first communication channel, the external host transmits the assembled data to the FPGA chip, performs digest operation and symmetric cryptographic operation processing and returns to the external host, and the security chip performs key management and asymmetric cryptographic operation on the received data Process and return to the external host through the FPGA chip; the second communication channel, the external host transmits the packaged data to the security chip for key management and cryptographic operations, and returns the processed data to the external host through the USB interface. The invention supports USB and mini PCI‑E two physical interfaces to work simultaneously without affecting each other by establishing two communication channels.

Description

technical field [0001] The invention relates to the technical field of encryption cards, in particular to a mini PCIE encryption card, a data communication system and a method. Background technique [0002] With the rapid development of communication and computer network technology, the rise of strategic industries such as the Internet of Things, big data, and cloud computing, people are increasingly dependent on the network environment and network information resources. get effective protection. In order to ensure the data security of special data or industries, network data needs to be transmitted in an encrypted manner. Generally, the encryption card integrated in the device is mainly responsible for the data encryption task. [0003] At present, the mini PCIE encryption card is a encryption card that supports the mini PCI-E interface. Although the mini PCI-E interface can support the USB communication protocol and the PCI-E communication protocol at the same time, when ...
