Usb data transfer port for secure transmission of encrypted data

Abstract

The present invention provides a USB data transmission port for secure transmission of encrypted data, which includes a USB socket connected to the PC end and a USB plug connected to the storage end, the USB socket is internally encrypted and the communication channel is disconnected in the initial state, and the USB plug can be connected to the storage port. The USB socket is matched and identified for docking and the USB plug is used to decrypt the USB socket so that the internal communication channel is turned on. The USB socket includes a mounting block, a data wire, an encryption mechanism with a switch function, and a protective shell, the mounting block, the data wire and The encryption mechanisms are all set in the protective shell one. One end of the data wire is connected to the PC end, and the other end is used to connect the USB plug. In the open state, the data wire is connected in series to the encryption mechanism. After the USB plug is matched with the USB socket for identification and docking, the USB plug can decrypt the encryption mechanism and prompt the encryption mechanism to switch from the off state to the on state.

Description

technical field [0001] The invention relates to the technical field of data encryption transmission, in particular to a USB data transmission port applied to secure transmission of encrypted data. Background technique [0002] USB, the abbreviation of Universal Serial Bus (Universal Serial Bus) in English, is an external bus standard used to regulate the connection and communication between computers and external devices. It is an interface technology applied in the PC field. The USB interface supports the plug-and-play and hot-swap functions of the device. USB was jointly proposed by Intel, Compaq, IBM, Microsoft and other companies at the end of 1994. With the development of technology, the Type-C USB interface comes out, which can support both front and back plugs, and transmits data with a strong signal. However, during the use of the USB port, for the sake of versatility and universality, it does not have an encryption function. After the USB plug and the USB socket ...

AI Technical Summary

Problems solved by technology

However, during the use of the USB port, for the sake of versatility and universality, it does not have an encryption function. After the USB plug and the USB socket are docked, the PC end and the storage end are directly matched and connected to form a conductive communication channel. Data transmission and interaction between the end and the storage end through this communication channel, because there is no encryption function, the risk of data leakage or theft is extremely prone to occur, and there are certain security risks

In order to overcome the technical defect that ordinary USB ports do not have encryption functions, it is necessary to provide a dual-code encrypted USB data transmission port that has an ingenious and compact structure, simple and reliable principles, encryption functions, and needs to be matched and identified to establish a communication channel.
