Problems solved by technology

Whether it is a software-encrypted or hardware-encrypted U disk, there are the following problems in use: there are still disadvantages that common information and classified information are mixed and difficult to manage and use; if the U disk is lost or stolen, the classified information cannot be self-destructed will lose effective security protection forever
These deficiencies of the popular encrypted U disks in the market are the key crux of the problem that currently plagues secret-related units to effectively use secure U disks.

Abstract

A safety storage system of U disc comprises master disc including USB chip in shell, monolithic computer connected with said chip, enciphering circuit connected to output port of monolithic computer, front pluggable unit and back pluggable unit at front and back of shell; subdisc including subdisc USB chip in subdisc shell, subdisc monolithic computer connected to said chip and front pluggable unit of subdisc at front of subdisc shell; enabling to hand master disc to user for using or holding it by user and to hand subdisc with secret information to concerning department for storing it there safety.

Description

Technical field: [0001] The invention relates to a safe U disk storage system device for confidential information. Background technique: [0002] Due to the needs of national information security, military units, government agencies and secret-related enterprises have already required a large number of encrypted U disks as mobile storage devices. Many domestic manufacturers have also increased the research and development of U disk security encryption technology and launched their own security encryption U disk storage system one after another. For example: Patriot Encrypted U Disk, T-LAND Free Encrypted U Disk, Suang Encrypted U Disk, Lexar Encrypted U Disk, Langke Encrypted U Disk, Xiaobawang Encrypted U Disk, Hanwang Encrypted Type U disk, etc., with dozens of products. These encrypted U disk storage devices can be divided into hardware encryption type and software encryption type. The basic method of the software encryption type is to preset a specific encrypted folde...
