Abstract
The present invention discloses a fast and reliable design method for destroying a SSD hard disk. The method for destroying the SSD hard disk is implemented by three steps of changing a data storage mode, a data reading/writing mode and a data destruction mode of the SSD hard disk. Compared to the prior art, in the fast and reliable design method for destroying the SSD hard disk, a data storage architecture, the data reading/writing mode and the data destruction mode of the SSD hard disk are changed, so that the rapidity and reliability of data destruction are ensured, and the data is effectively prevented from being maliciously tampered, stolen and leaked.
Description
Technical field
The present invention relates to hardware destroy technical field, specifically a kind of fast and reliable destroys the method for designing of SSD hard disk.
Background technology
SSD hard disk, is called for short solid dish, solid state hard disc (SolidStateDrive) and the hard disk made with solid-state electronic storage chip array, be made up of control module and storage unit (FLASH chip, dram chip).SSDCONTROLLOR and solid-state hard disk controller.
Current, data security is more and more taken seriously, in recent years, the event that hard disk information is divulged a secret also emerges in an endless stream, therefore, hardware destroy technology becomes the especially military active demand of individual and enterprise, present hardware destroy technology is general and various, for SSD hard disk, traditional SSD can destroy hard disk and conventional SSD hard disk basic indifference in reading and writing data mode, which results in data storage and still has certain rule to follow, so when data destroying, all data covers must be fallen, otherwise data will be reduced easily.The most general destroy technology is exactly by the whole erasings one by one of FLASH data, in covering " 0 " or " 1 ", this kind of mode is safe and reliable, but for the SSD hard disk of larger capacity, the time taking a few minutes possibly completes this operation, this is acceptable for domestic consumer, but for emergency condition, this time is just too very long.Therefore, it is possible to the reliable SSD hard disk destroyed fast becomes a kind of demand in emergency circumstances.
Disclosed patent application document: number of patent application is " CN201010595945.4 ".Name is called " destroy device of hard disk, CD and semiconductor storage body "; this document disclose that " destroy device of a kind of hard disk, CD and semiconductor storage body, it is destroyed mechanism, discharging mechanism, power source feeding mechanism by feed mechanism, pressure, automatically to be controlled and safety guard etc. forms.Adopt the destroy device of the hard disk of said structure, CD and semiconductor storage body, can destroy thoroughly overall device such as hard disk, CD and the semiconductor storage bodies put between pressure destruction mechanism's dynamic pressure head and static pressure head, reach the requirement that classified document is destroyed.This equipment can make concerning security matters personnel can in person destroy above-mentioned confidential document and carrier thereof whenever and wherever possible, and that avoids the contact of unrelated person to cause divulges a secret.This equipment have easy to use, safe and reliable, be easy to the features such as maintenance.The operation of equipment to environment also without any harm ".
Number of patent application is " CN201410819023.5 ".Name is called " method of the irreversible self-destruction of a kind of solid state hard disc Long-distance Control power down preventing ", this document disclose " method of the irreversible self-destruction of a kind of solid state hard disc Long-distance Control power down preventing; the method step is as follows: under normal operating conditions; solid state hard disc normally works, carries out storage by the SSD controller NANDFLASH controlled in external data and solid state hard disc and transmits; When needs perform solid state hard disc self-destruction, send self damaging order to the telecommunication control module on solid state hard disc by the mode of remote radio communication; Telecommunication control module sends destruction instruction to the self-destruction control module in solid state hard disc, and self-destruction control module performs self damaging order, realizes self-destruction to solid state hard disc; Afterwards, the self-destruction control module in solid state hard disc can feed back self-destruction status information, and remote control communication module feeds back self-destruction execution state information by telecommunication mode to control people again.The present invention controls solid state hard disc by telecommunication and performs self-destruction, avoids data maliciously to be altered, steal or leak under special, the harsh conditions such as without permission ".
Above-mentioned open file, although can destroy hard disk, the SSD hard disk for larger capacity is difficult to destroy fast at short notice, thus prevents data from maliciously being altered, steal or leaking.
summary of the invention
Technical assignment of the present invention is to provide the method for designing that a kind of fast and reliable destroys SSD hard disk.
Technical assignment of the present invention realizes in the following manner, and the method for described destruction SSD hard disk is by changing the data storage method of SSD hard disk, the read-write mode of data, and destruction mode three step of data realizes;
The data storage method of SSD hard disk: when SSD hard-disc storage data, utilizes the algorithm of encryption, the memory address of data is carried out superencipherment in SSD hard disk controller, by continuous print Data Segmentation poling fritter;
The read-write mode of data: when SSD hard disk carries out reading data, first system directive is changed by key algorithm by SSD hard disk controller, then by the digital independent of appropriate address out, finally the data of reading be placed on RAM inner buffer and send to main frame;
The destruction mode of data: when SSD hard disk carries out data destroying, first press destruction button, after SSD hard disk controller receives the triggering level of data destroying, the data address translation cipher key destruction of SSD hard disk controller inside will be stored at once, once after key destroyed, the data being stored in SSD hard drive internal will become a heap of a loose sand, can not read any valid data, and SSD hardware destroy is complete.
In the data storage method of described SSD hard disk, before SSD hard-disc storage data, want first storage key in SSD hard disk controller.
In the data storage method of described SSD hard disk, disperse to be stored in different FLASH by after continuous print Data Segmentation poling fritter.
Compared to the prior art a kind of fast and reliable of the present invention destroys the method for designing of SSD hard disk, change the storage architecture of the data of SSD hard disk, the read-write mode of data, and the destruction mode of data, guarantee the rapidity of data destroying, and reliability, effectively prevent data from maliciously being altered, steal or leaking.
