Insert master pairing sign indicating number 18 and master pairing authentication software 19 in master 1 single-chip microcomputer 12 of described safe U disc storage system device in advance, insert bracket panel pairing sign indicating number 28 in the bracket panel single-chip microcomputer 22 of bracket panel 2 in advance, and bracket panel self-destruction control and treatment software 30.
The master 1 of described safe U disc storage system device and bracket panel 2 form cascade operation, and wherein master 1 is identical with the use of conventional USB flash disk, and can be independent of bracket panel 2 work; And bracket panel 2 must be cascaded on the master 1 of unique pairing, and the user can conduct interviews to canned data in the bracket panel 2.
The assurance of the master 1 of described safe U disc storage system device and bracket panel 2 uniquenesss pairing derives from and utilizes between the single-chip microcomputer 12 of master and each self-embedding of bracket panel and the bracket panel single-chip microcomputer 22 that tight pairing authentication processing mechanism guarantees between pairing sign indicating number 18 and the bracket panel pairing sign indicating number 28, when forming the cascade state between master 1 and the bracket panel 2, master authentication software 19 operation automatically mates authentication, only when authenticate by after bracket panel 2 normal visit just is provided.
All deposit the encryption that information in the bracket panel 2 is all passed through master 1 encrypted circuit 13 in advance in safe U disc storage system device of the present invention, and all information of reading from bracket panel 2 are all handled through the deciphering reduction of master 1 encrypted circuit 13.
The bracket panel self-destruction software 30 of the bracket panel 2 of safe U disc storage system device of the present invention will move and cause all automatic removings of canned data in the bracket panel 2 automatically when satisfying the condition of setting in advance under setting the self-protection state.
Using method of the present invention is as follows:
1. non-classified information is stored in master, classified information is stored in bracket panel after encryption, and the concerning security matters characteristic implementation different with bracket panel separates preservation according to master.
2. carry classified information and go on business in the process, the major-minor dish can be separated and transfer to different people and carry respectively, only when formal the use, implement the pairing authentication.
When storage carry out respectively by the major-minor dish of classified information official post with before, the condition that bracket panel carries out the information self-destruction is set is provided with, in the use, bracket panel will carry out self-destruction to the classified information of storage according to the specified conditions that are provided with to be handled.
Result of use of the present invention is:
1. master can give user's routine to use and preserve, the bracket panel that stores classified information then can separate with master transfers to special administrative authority as the strict keeping of concerning security matters memory device, solve thus present concerning security matters personnel when using existing USB flash disk at needs simultaneously to routine information and classified information operation with preserve the inconvenience and the insecurity of especially carrying when going out;
2. classified information carries in the process of going on business, and the major-minor dish separates and transfers to different people and carry respectively, only implements pairing when formal the use, carries the probability of crime because of the individual to reduce classified information;
3. be in when carrying out official post respectively and using state when device, bracket panel classified information self-destruction with good conditionsi is handled, and can effectively prevent because of the classified information that bracket panel is lost or the cause stolen back generation of divulging a secret.
