Abstract
The present invention provides a portable storage device with a secure encryption function. The device comprises a data storage unit, a physical data communication port allowing communication between the data storage unit and the external, a control unit connected with the data storage unit, and a wireless data reading unit connected with the control unit, wherein the control unit controls data to write into the data storage unit or reads data inside the data storage unit, the control unit is connected with the physical data communication port and controls the physical data communication port to transmit data, and the wireless data reading unit reads authentication data sent from an external device and sends the authentication data to the control unit. A beneficial effect of the portable storage device disclosed by the present invention is using NFC (Near Field Communication) to perform encryption on the portable storage device, so as to improve safety of the portable storage device.
Description
Technical field
The invention belongs to portable storage device field, especially relate to a kind of portable storage device with safe encryption function.
Background technology
In existing technology, USB flash disk is portable storage device conventional in life; it has the advantages that capacity is big, volume is little, easy to carry; but cause it to be easily lost just because of these features; once lose; the vital document being stored in USB flash disk will have the risk obtained by other people; although present USB flash disk has encryption function, but is mostly read-write protection, it is impossible to realize real safety certification. There is the technical problems such as confidentiality difference, safety be low.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of portable storage device with safe encryption function, is especially suitable for USB flash disk is encrypted.
For solving above-mentioned technical problem, the technical solution used in the present invention is: a kind of portable storage device with safe encryption function, including data storage cell, make the physical data communication interface of data storage cell communication with the outside world, the control unit being connected with data storage cell, described control unit controls data write data memory element or reads the data within data storage cell, described control unit is connected the data transmission controlling physical data communication interface with physical data communication interface, the wireless data being connected with control unit reads unit, described wireless data reads unit and reads the authentication data of external equipment transmission and authentication data is sent to control unit.
Further, described physical data communication interface is USB interface.
Further, described physical data communication interface is Micro-USB interface.
Further, described wireless data reads unit is that NFC data reads unit.
Further, described data storage cell is flash memory.
The present invention has the advantage that and has the benefit effect that USB flash disk user can use the handheld device having NFC function that USB flash disk is carried out safety certification owing to adopting technique scheme; There is the advantages such as easy to use, safe.
Accompanying drawing explanation
Fig. 1 is the structured flowchart of the present invention.
Detailed description of the invention
As shown in Figure 1, a kind of portable storage device with safe encryption function of the present invention, including data storage cell, make the physical data communication interface of data storage cell communication with the outside world, the control unit being connected with data storage cell, control unit controls data write data memory element or reads the data within data storage cell, control unit is connected the data transmission controlling physical data communication interface with physical data communication interface, the wireless data being connected with control unit reads unit, wireless data reads unit and reads the authentication data of external equipment transmission and authentication data is sent to control unit, physical data communication interface is USB interface, physical data communication interface is Micro-USB interface, it is that NFC data reads unit that wireless data reads unit, data storage cell is flash memory.
The work process of this example: during first use portable storage device, user can use the handheld wireless communication device (such as mobile phone) having NFC function to arrange authentication data, handheld wireless communication device is pressed close to portable storage device, now the NFC data within portable storage device reads unit and will read the authentication data that handheld wireless communication device sends, and this authentication data is sent to control unit, control unit stores this authentication data, namely completes the setting of authentication data, when reusing USB flash disk, the handheld wireless communication device being provided with authentication data is pressed close to portable storage device, NFC data reads unit and reads the authentication data that handheld wireless communication device sends, and this authentication data is sent to control unit, the authentication data of acceptance is compared by control unit with storage authentication data therein, if two authentication datas are consistent, then certification is passed through, the data transmission between data storage cell and external equipment can be carried out, if two authentication datas are inconsistent, authentification failure, data transmission between data storage cell and external equipment is prohibited.
Above one embodiment of the present of invention is described in detail, but described content has been only presently preferred embodiments of the present invention, it is impossible to be considered the practical range for limiting the present invention. All equalizations made according to the present patent application scope change and improvement etc., all should still belong within the patent covering scope of the present invention.
