Damage method.
Background technology
Constantly promoting along with data value and memory technology development, the importance of storage system constantly promotes, number
According to becoming most crucial assets.Storage system, as the shelf space of data, is the last line of defense of data protection；Along with depositing
Storage system is developed to networking and distributed direction by this locality is direct-connected, and is shared by the numerous computers on network, makes storage
System becomes more prone under attack, and the storage system of relative quiescent often becomes the preferred object of assailant, reaches to steal, distort
Or the purpose of destruction data, without storage safe precaution measure, once assailant successfully penetrates into data-storage system
In, its negative effect will be inestimable, and therefore storage safety becomes most important.
Disclosed Patents file: entitled " a kind of solid state hard disc data destroying system ", this document discloses " a kind of
Solid state hard disc data destroying system, it is a kind of safety in order to protect the data being stored in solid state hard disc, prevents solid-state
Data in hard disk are stolen, it is possible to detect the stolen danger of data and destroy the solid state hard disc data destroying system of data.With existing
Having technology to compare, the present invention provides the software and hardware integrated system of a kind of solid state hard disc data destroying, in order to protect solid state hard disc
In data, once have the illegal action opening hard disk package casing, will automatically start data destroying circuit, wipe solid-state
Data in hard-disc storage granule, thus reach the effect of assuring data security ".
Entitled " band rapid data is from the solid state hard disc destroying function ", this document disclose " a kind of band rapid data from
Destroy the solid state hard disc of function, belong to the rapid data in solid-state storage and destroy technical field.The present invention passes through the soft destruction of data
Firmly destroying two kinds of destruction modes with data and realize the data destroying of solid state hard disc, wherein the soft Destruction of data is: opened by triggering
Close and apply low level pulse signal, perform the data destroying in hard disk controller, it is achieved the formatting of storage content；Data are sold firmly
The process of ruining is: applied to encryption solid state hard disc and the destroying method SH thereof of a FL timed destroying function by power conversion chip
The method of high pressure destroys the performance of storage medium own to reach to destroy the purpose of data.Two destroy common the realization quickly that cooperate
Data destroying function, eliminates the potential safety hazard of critical data.The destruction speed of the present invention is fast, simple to operate, greatly reduces solid
State hard disk cost ".
File disclosed above solves the technical problem that from present invention used technological means is different.
Summary of the invention
The technical assignment of the present invention is to provide encryption solid state hard disc and the destroying method thereof of a kind of timed destroying function.
The technical assignment of the present invention realizes in the following manner, and this solid state hard disc is by hard disk controller, RTC, gating electricity
Road, Flash, flash array and lithium battery composition；
Hard disk controller is connected with RTC, gating circuit, Flash and flash array respectively by data；
Lithium battery is connected with hard disk controller, RTC and gating circuit respectively by power path；Gating circuit is led to by power supply
Road is connected with Flash, flash array respectively.
After its exterior powers power down, this destroying method flow process is as follows:
1) lithium battery is system power supply, it is ensured that writing back of desired data；
2) the clock strategy write RTC after hard disk controller will be preset, controls gating circuit and makes Flash and flash array power down,
Self enters low-power consumption mode, and RTC starts timing；
3) RTC timing is to after preset value, and hard disk controller is waken up, and controls gating circuit on Flash or flash array simultaneously
Electricity, and destroy needing the data destroyed to carry out erasing.
The preset value of described timing is one or two.
When the preset value of described timing has a preset value, hard disk controller controls gating circuit to Flash and flash memory
Array is powered simultaneously, and wipes the cryptographic key factor in Flash and the data in flash array, reaches thoroughly to destroy.
When the preset value of described timing has two preset values, when reaching first preset value, hard disk controller controls
Gating circuit only powers on to Flash, and wipes the cryptographic key factor in Flash, makes hard disc data to decipher；Only manager
After recovering cryptographic key factor for user, the most read-write data；When reaching second preset value, hard disk controller controls gating circuit and gives
Flash and flash array are powered simultaneously, and wipe the cryptographic key factor in Flash and the data in flash array, reach thoroughly to sell
Ruin.
Compared to the prior art the encryption solid state hard disc of a kind of timed destroying function of the present invention and destroying method thereof, have
The feature such as reasonable in design, esy to use, safe and reliable, it is possible to effective ensure the complete, without damage of user data information
Simultaneously, it is provided that the means not being stolen.
Accompanying drawing explanation
Accompanying drawing 1 is the structured flowchart of the encryption solid state hard disc of a kind of timed destroying function.
Detailed description of the invention
Embodiment 1:
This solid state hard disc is made up of hard disk controller, RTC, gating circuit, Flash, flash array and lithium battery；
Hard disk controller is connected with RTC, gating circuit, Flash and flash array respectively by data；
Lithium battery is connected with hard disk controller, RTC and gating circuit respectively by power path；Gating circuit is led to by power supply
