USB data transmission port applied to secure transmission of encrypted data

Abstract

The invention provides a USB data transmission port applied to secure transmission of encrypted data. The USB data transmission port comprises a USB socket connected with a PC end and a USB plug connected with a storage end. The interior of the USB socket is encrypted, and a communication channel is disconnected in an initial state; the USB plug can be matched, identified and butted with the USB socket; the USB plug is used for decrypting the USB socket, so that an internal communication channel of the USB socket is conducted; the USB socket comprises a mounting block, a data wire, an encryption mechanism with a switching function and a protective shell I; the mounting block, the data wire and the encryption mechanism are all arranged in the protective shell I; one end of the data wire isconnected with the PC end, and the other end is used for the butt joint of the USB plug. The encryption mechanism is set to be in an off state and an on state which can be switched to each other and is in an off state in an initial state. The data wire is connected with the encryption mechanism in series. After the USB plug and the USB socket are matched, recognized and in butt joint, the USB plugcan decrypt the encryption mechanism and promote the encryption mechanism to be switched 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.
