The utility model discloses a theory of operation is:

the utility model relates to a machine carries antidetonation small-size electronic disk combines together GPS and the dual physics of RFID encryption, is that I department once great attempt and breakthrough in the aspect of solid state hard disk security, and the product combines the current technique in the aspect of industry military project field of I department, has made very big promotion to the quality of SSD itself. The SSD encryption technology is still in a development stage in China, and no mature product combining GPS and RFID dual physical encryption exists in the market;

the research on the safe use technology of the solid state disk is in the initial development stage at present, the SSD designed by the department combines the RFID technology with the GPS technology, the defect that the solid state disk is easy to crack due to pure password encryption is overcome, the reading and writing operation of the SSD by a user who succeeds in authentication is allowed through the dual authentication of the GPS and the RFID,

because GPS lacks absolute security and reliability, the region which is not authenticated by GPS or the region without GPS signals can still be authenticated by RFID technology to perform read-write operation on SSD, and other authentication use modes of the hard disk are provided for users under the condition of ensuring security;

the GPS area is used for first-layer protection and is used for identifying whether the SSD is used in a legal area, the SSD can be simply and conveniently used when the area is legal, other complex authentication is required when the area is illegal, and the SSD can be used only when the area is legal,

the RFID area, which is used for the second re-authentication, must also pass the authentication area, this part will not use SSD without we,

a storage area in which a user can perform encrypted storage of a file,

the whole system is integrated by the MCU, and the reasonable algorithm can not cause any influence on the reading and writing speed of the system,

the working process is as follows:

the SSD is powered on, the GPS module and the MCU module are powered on, the GPS receives the current position information and transmits the current position information to the MCU, and the MCU judges whether the current position information is a legal area or not after receiving the current position information

1, the RFID card reading area starts to work when the area is legal, and when a legal area key transmitted by the RFID card is consistent with an MCU built-in key, the RFID card is transferred to a storage area, so that the SSD can work normally; if the keys are not matched, the SSD cannot be read and written, the SSD triggers write protection or data destruction,

2, if no GPS signal exists or the RFID card reading area is in an illegal area, the RFID card reading area receives the 'illegal area key' transmitted by the RFID card and the key built in the MCU, the RFID card reading area turns to an SSD guide area, the guide area can manually input a password, the password turns to a storage area correctly, the password is wrong and the input times exceeds the specified times, the guide system exits, and the SSD cannot be used if the butt joint is not matched;

the device improves the safety encryption effect of the SSD, and the high-safety solid state disk combining the RFID technology and the GPS technology; the device is provided with an internal shockproof structure, so that the stability of the device can be protected when the device is vibrated by the host during working, and a good product scheme is provided for customers with special requirements in the field of SSD use positions.
