The data self-destructive electronic hard disk has an important value for self-destruction of data of unmanned equipment and equipment easy to lose (such as secret involved carriers).
Description
Technical field
But the utility model relates to a kind of electric board of data self-destruction.
Background technology
Along with the development of electronic information technology, information security more and more comes into one's own, and for guaranteeing can effectively to destroy data message in special moment, many companies have applied for the self-destruction technical patent of multiple electric board.But the self-destruction that these technology realize all needs to satisfy one of following two aspect conditions:
(1) " self-destruction " must be triggered by the people, destroy data as being triggered by button, software command, wireless instructions etc. by the holder of electric board, namely must " people is (Man in the loop) in the loop ".
(2) electric board is in the situation that there is externally fed, at the illegal key of input, disassembled (but not destroying self-destruct circuit) etc. by illegal holder and trigger and destroy data.
There is following shortcoming in the self-destruction technology of above-mentioned existing electric board:
(1) can not effectively control the situation of electric board to the holder,, electric board loss out of hand such as unmanned machine is stolen etc., and owing to not sending self damaging order to electric board, self-destruction was lost efficacy.
(2) there is no externally fed, data message just can't be destroyed, and illegal holder has the sufficient time to crack, and by the self-destruct circuit of destroying electric board, self-destruction is lost efficacy.
Summary of the invention
The utility model provides a kind of electric board that carries out the data self-destruction, and mainly having solved prior art can't be when breaking away from externally fed or holder and can not effectively control electric board, and electric board carries out the problem of effective self-destruction.
Concrete technical solution of the present utility model is as follows:
This electric board comprises data storage device, equipment end wireless communication apparatus and external interface, also comprise for when breaking away from externally fed to electric board in all devices power supply of powering, the power sense circuit that is used for electric quantity of power supply is detected, be used for and wireless device that the equipment end wireless communication apparatus is shaken hands, be used for receiving the data processing equipment whether radio communication device signal and electric quantity of power supply signal and analyzing and processing generate the self-destruction signal and send self damaging order to memory storage; Described power supply is connected with memory storage by power sense circuit, data processing equipment successively, and wireless device is connected with memory storage by data processing equipment.
Above-mentioned data storage device comprises FLASH storage array and Memory Controller.
Above-mentioned power supply is connected with data processing equipment with data storage device by voltage conversion circuit.
Control external power supply when above-mentioned power supply comprises battery and is connected the connection external power supply battery is charged, the power control circuit of powering to other devices by voltage conversion circuit when breaking away from power supply.
Above-mentioned external interface comprises data-interface, power interface and wireless signal interface.
Above-mentioned data-interface can adopt the standard storage interfaces such as USB interface, PATA interface, SATA interface.
The utility model has the advantage of:
But the electric board that is somebody's turn to do the data self-destruction is mainly must provide externally fed and necessary " people is in the loop " two kinds of defectives for current electric board self-destruction, but the electric board that is somebody's turn to do the data self-destruction can guarantee can not effectively control electric board in the situation that break away from externally fed, holder, carries out the self-destruction of electric board.This technology has important value to the self-destruction of unmanned machine, easy equipment (as the concerning security matters carrier) data of losing.
Description of drawings
Fig. 1 is the utility model structure principle chart.
Embodiment
The principle of work of this electric board self-destruction is:
A) when reaching one of following trigger condition, electric board starts self-destruction:
(1) electric quantity of power supply is low, and the holder does not process at the appointed time;
(2) electric board can not be completed with the equipment end radio communication device by its wireless device and shake hands, as can't detect handshake or the wrong cipher key of shaking hands.
B) reach trigger condition after, send self damaging order by processor and peripheral circuit to Memory Controller.
C) after Memory Controller is received self damaging order, wipe the data of FLASH storage array;
D) in said process, even battery has guaranteed to break away from externally fed, electric board still can normally be carried out self-destruction.
In order to ensure the more effective self-destruction of electric board; can multiple trigger condition combination; design multiple trigger circuit, as timer (regularly self-destruction), voltage monitor (cell voltage hangs down self-destruction), trigger switch (self-destruction of electric board separation instrumentation), shell protection gauze (disassembling self-destruction), shock sensor (the electric board self-destruction is taken out in violence) etc.
Below in conjunction with drawings and the specific embodiments, the utility model is described in detail:
This electric board that can carry out the data self-destruction by FLASH storage array, Memory Controller, testing circuit, wireless device, equipment end radio communication device, data processing equipment, voltage conversion circuit, battery, power control circuit, equipment interface totally 10 parts form.Functions is as follows:
A) the FLASH storage array is responsible for the storage of data, and can be according to the command erases data of Memory Controller.
B) Memory Controller is responsible for carrying out read-write to the FLASH storage array, is wiped.
C) testing circuit is one of principal character of present technique, can detect battery electric quantity.When electric quantity of power supply is low, by wireless module, send alarm to the equipment end wireless communication module, notify the holder to process within a certain period of time, exceed that the time processes, namely reach the self-destruction trigger condition.
D) wireless module mainly by adopt wireless signal with the equipment end radio communication device shake hands, when can complete when shaking hands, the electric board normal operation; When can't detect handshake or shake hands wrong cipher key, namely reach the self-destruction trigger condition.
