Abstract

The invention relates to the technical field of information safety, in particular to a safe leading-in device, system and method for USB data. The safe leading-in device for the USB data comprises a main processing chip. The main processing chip comprises a main interface connected with a U disk, an auxiliary interface connected with a PC chip, a serial port connected with a debugging module, a Flash module and an internal storage chip, the Flash module is in bothway signal transmission with the main processing chip, and the Flash module is inserted into the linux system. The invention further provides the safe leading-in system and method for the USB data. Safe, fast and one-way big data leading in can be achieved in the current mobile storage medium safety management field, the efficiency of safely leading extranet data in the intranet is effectively improved on the premise of guaranteeing the safety of the intranet through the technical measures such as identity authentication, behavior auditing, Trojan virus defense and jurisdiction control, and the information safety requirement in the informatization application is met.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a USB data security importing device, system and method. Background technique [0002] In the prior art, the USB data security importing device is used for data security exchange products. At present, certain researches have been carried out on the issue of data security exchange at home and abroad, and the State Secret Bureau of China's secret computer has proposed an optical one-way in the three-in-one product. Import equipment, through which the external network data can be unidirectionally imported into the confidential computer through the U disk. The cost of this product is relatively high, and there are certain limitations on the transmission efficiency. Aiming at the problem of sensitive industry network data security exchange, a dedicated secure USB flash drive is proposed. The dedicated secure USB flash drive adopts technical means such as data encryption ...
