Description
Technical field
The present invention relates to data processing field, is related to the scheme that a kind of WIFI remote controls solid state hard disc is destroyed.
Background technology
Current, the data effectively taken precautions against in solid state hard disc leak, while computer hardware anti-theft measure is strengthened, mainly
It is to prevent the sensitive data from leaking by way of to data encryption.But any AES has its relativity,
It can completely obtain in hard disk on the basis of all data, as cracking trajectory and technology develop, sensitive data all the time be present and let out
The hidden danger of leakage.
Traditional mechanical hard disk storage medium is magnetic material.When W head is to disk write-in data, it will can magnetize
The signal of data bit is adjusted to some appropriate intensity, but signal is not more strong better, should not exceed certain boundary, Yi Mianying
Ring adjacent data bit.Because signal intensity is insufficient to allow storaging medium to reach the magnetized state of saturation, so physical record exists
Signal on medium is influenceed by the previously saved signal in same position, if for example, the data bit recorded originally is 0,
Now by one 1 covering, then signal intensity of the physical record in disk medium certainly not as original data bit be 1 it is strong
Degree.Special hardware device can accurately detect out the actual value of signal intensity, and this value is subtracted to the mark of current data position
Quasi- intensity, the copy of capped data is just obtained.In theory, this process can recursion seven times forward.Therefore, for tradition
For hard disk, even if carry out low-level formatting (within seven times) repeatedly, its data still can be resumed.
System is facilitated user's initialization system and is implemented to wipe using the remote anti-theft design based on WIFI radio receiving transmitting modules
Remove, flexibility is higher.This invention is implemented, it is necessary to has matched customization USB flash disk to realize, makes it using by certain
Limitation.The storage medium of solid state hard disc is NandFlash, and NandFlash internal storage units are three terminal device, respectively source
Pole, drain and gate, unlike metal-oxide-semiconductor, the three terminal device is double-grid structure, is added between grid and silicon substrate
One floating grid.During read-write, electric charge is injected into floating boom and represents to write 0, electric charge is not injected into and represents 1.It is hard with tradition
Unlike disk, as long as NandFlash is wiped 1 time, data can not be recovered.
In some security applications, solid state hard disc internal data needs to be destroyed rapidly.A kind of it has been proposed that physical destroying
Technology.By adding 10V voltages on NandFlash, puncture its internal structure, complete the thorough destruction to NandFlash.
Above-mentioned destroying method method has the shortcomings that very big：
When high voltage on NandFlash is destroyed, by test, by taking Samsung K9LBG08U0M as an example, immediate current will
Reach 3 to 4 amperes, if including 8 NandFlash on a solid state hard disc, then immediate current is up to more than 30 amperes, to mark
For 2.5 cun of accurate solid state hard discs, its sata interface and PCB can not be by so big electric currents, and security performance is low, easily
Burn out interlock circuit and component.
The content of the invention
The present invention provides a kind of solid-state hard disk destroyer, to solve the problems, such as be how safely, effectively, it is rapidly right
Solid state hard disc is destroyed.
The present invention provide using WIFI agreements solid state hard disc secrecy system and method method, the system by antenna 101,
WIFI radio receiving transmitting modules 102, MCU module 103, PCIE/SATA protocol converters 104, PCIE interfaces 105, power module
A106, SATA controller A107, Flash array A108, power module B109, SATA controller B110 and Flash array B111,
Pulse voltage occurs circuit and destroys interface composition..
The function of the described module of antenna 101 is to receive user mobile phone to be sent to information signal and transmitting by wireless base station
WIFI radio receiving transmitting modules 102 are sent to information signal.
WIFI radio receiving transmitting modules 102 are responsible for receiving and sending information；
MCU module 103 is the nucleus module of the present invention, is responsible for the various operational orders of processing user, and is sent out according to user instruction
Erasing signal and locking signal are sent, to realize the lock function of the present invention, erasing function, first erasing relocks function.
The function of the described module of antenna 101 is to receive user mobile phone to be sent to information signal and transmitting by wireless base station
WIFI radio receiving transmitting modules 102 are sent to information signal.
WIFI radio receiving transmitting modules 102 are responsible for receiving and sending information；
MCU module 103 is the nucleus module of the present invention, is responsible for the various operational orders of processing user, and is sent out according to user instruction
Erasing signal and locking signal are sent, to realize the lock function of the present invention, erasing function, first erasing relocks function.
Specifically, when user sends lock instruction, MCU module 103 reads user from WIFI radio receiving transmitting modules 102
The lock instruction of transmission, locking signal A is set to enabled state by MCU module 103, while locking signal B is set into enabled shape
State, now, off-position is in by the power module A106 SATA controllers 107 powered and Flash arrays 108, for using
For person, the data stored on Flash arrays 108 are sightless, on the contrary, the SATA controller powered by power module A109
110 and Flash arrays 111 are in power supply state, and for the user, the data being pre-stored within Flash arrays 111 are
It is visible, this ensure that the security of confidential data；When user sends erasing instruction, MCU module 103 is wirelessly received from WIFI
Hair module 102 reads the erasing instruction of user's transmission, and locking signal A is maintained former enabled state constant, wiped by MCU module 103
Except signal A is set to effectively, triggering SATA controller A107 erasing function, SATA controller A107 will be held to Flash arrays 108
The irrecoverable security for arrive erasing operation, ensureing data with this of row, it is certainly this wipe be it is irrecoverable arrive, even if user
The disk is fetched again, can not also recover data；When user, which sends erasing, relocks instruction, MCU module 103 is wirelessly received from WIFI
The erasing that hair module 102 reads user's transmission relocks instruction, and locking signal A is maintained former enabled state not by MCU module 103
Become, erasing signal A is set to effectively, and triggering SATA controller A107 erasing function, SATA controller A107 will be to Flash arrays
108 execution are irrecoverable to arrive erasing operation, and then locking signal A is set to enabled state by MCU module 103, while will locking
Signal B is set to enabled state, now, is in disconnected by the power module A106 SATA controllers 107 powered and Flash arrays 108
Electricity condition, for the user, the data stored on Flash arrays 108 are sightless, on the contrary, by power module A109
The SATA controller 110 and Flash arrays 111 of power supply are in power supply state, for the user, are pre-stored within Flash
Data on array 111 are visible, and dual operation can preferably ensure the security of user data.Preferably, it is of the invention
SATA controller be INDILINX companies Barefoot ECO controllers.Control pulse voltage that circuit occurs.
Electric route test control occurs for pulse voltage, produces correct pulse voltage.
Preferably, the solid-state hard disk destroyer has following following features：The pulse voltage sent, amplitude 10
