Embodiment Construction

[0011] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0012] Please refer to the attached figure 1 , a USB data transmission method of the present invention, the method is as follows:

[0013] A buffer is set between the USB device and the USB host, and the data passing through the buffer is logically calculated by the MCU, so that the data output from the buffer can only be read, and information cannot be written.

[0014] The data that described USB device receives forms PCI-E data flow, is stored in RAM;

[0015] The MCU forms the read-only PCI-E data stream stored in the RAM through logic calculation with the PCI-E data stream stored in the RAM;

[0016] Then the read-only PCI-E data in the RA...

Abstract

The invention discloses a USB data transmission method. According to the method, a buffer area is provided between a USB device and a USB host, logical calculation is carried out on data, which pass through the buffer area, through an MCU, data output from the buffer area are enabled to be read only, and information cannot be written into the same. Data received by the USB device form a PCI-E data stream, and the PCI-E data stream is stored in a RAM; the MCU uses the PCI-E data stream, which is stored in the RAM, to form a read-only PCI-E data stream through logical calculation, and stores the same in a RAM; and then the read-only PCI-E data stream in the RAM is transmitted to a display device via the USB host. The method can ensure the transmission security of data information.

Description

technical field [0001] The invention relates to the technical field of USB, in particular to a USB data transmission method. Background technique [0002] At present, USB mobile storage has been widely used, which brings great convenience to people's life. What follows is the threat to data security, which is gradually increasing. People put forward more demands on data security. For special occasions with extremely high data security requirements, there is also a great demand for USB data transmission technology. However, due to security considerations, the common USB transmission technology solution obviously cannot meet its needs. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a USB data transmission method. [0004] In order to solve the problems of the technologies described above, the present invention is realized by the following scheme: a USB data transmis...
