Data security transmission interface device, system and method

Abstract

The invention provides data security transmission interface equipment. The interface equipment comprises a first partition and a second partition; the first partition is provided with a bootstrap program; and the second partition is used for storing encrypted data encrypted by the bootstrap program. According to the data security transmission interface equipment, the data and the bootstrap program are stored in different partitions, the second partition can be accessed only by the bootstrap program passing through the first partition, and the data written into the second partition is encrypted, so that the privacy of storage is improved, the probability of data leakage is reduced, and the situation that the data written into the data storage partition is maliciously string-changed or a malicious file is introduced to cause equipment failure is avoided.

Description

technical field [0001] The invention belongs to the technical field of data security, and in particular relates to a data security transmission interface device, system and method. Background technique [0002] Mobile interface devices are usually used to realize fast and portable data copy transmission. In the prior art, commonly used mobile interface devices are mobile hard disks, USB flash drives, and the like. Mobile devices generally use the USB interface for data transmission. USB serial bus technology is an interface technology applied in the field of PC, which realizes standardized data communication between the computer and external devices such as U disk and mouse, and is responsible for periodic data stream transmission between the host computer and U disk with constant transmission rate. [0003] Commonly used interface devices are plug-and-play devices, and generally access the interface devices directly through interactive graphical user interface terminals, ...

Problems solved by technology

This method leads to poor data confidentiality of the interface device, which is easy to cause data theft

At the same time, because the interface device is generally a mobile device, which is used multiple times among multiple devices, the privacy is poor, and it is easy to cause virus infection, which poses a great threat to industrial equipment with high security requirements.

[0004] In addition, the encrypted content and non-encrypted content in the existing encrypted U disk are stored in the common partition, and reading and writing operations on the two will also cause virus intrusion

[0005] For special projects with high requirements for on-site construction in the field of rail transit, the use of existing mobile interface devices for data copying cannot meet the requirements
