Abstract
The utility model discloses an encrypted universal serial bus (USB) flash drive. The encrypted USB flash drive comprises a shell, a core which is arranged in the shell, and a USB interface which is formed at the right end of the shell, wherein the core consists of a printed circuit board (PCB), a singlechip, two data memories, a resistance-capacitance resistor, a crystal oscillator, an encryption and decryption module and a flash chip; and the USB interface is connected with the PCB. The encrypted USB flash drive has the advantages that by adoption of the two data memories, memory capacity can be improved, and classification of memory contents can be realized; by adoption of the encryption and decryption module, the safety of the memory contents can be ensured; by adoption of the flash chip, the encrypted USB flash drive is funny in use, and attractiveness is improved; and the aims of large memory capacity, classification of the memory contents, simple structure and attractiveness in appearance are fulfilled.
Description
Technical field
But the utility model relates to a kind of encrypted U disk.
Background technology
At present, USB flash disk because of small and exquisitely be easy to carry, memory capacity is big, low price, dependable performance, the first-selected gift present of Cheng Liao company, unit and tissue, promotional item, but existing USB flash disk aesthetics is poor, information storage can not be classified.
Summary of the invention
It is bigger that the technical matters that the utility model will solve provides a kind of storage volume, and stored contents can be classified, and is simple in structure, but the encrypted U disk of good looking appearance.
The utility model is realized through following technical scheme: comprise shell; And setting movement in the enclosure; And be arranged on the USB interface of shell right-hand member; Said movement is made up of pcb board, single-chip microcomputer, two data reservoirs, capacitance-resistance resistance, crystal oscillator, encryption and deciphering modules and flash chip, and said USB interface is connected with pcb board.
Further; Said single-chip microcomputer, two data reservoirs, capacitance-resistance resistance, crystal oscillator, encryption and deciphering modules and flash chip are welded on the pcb board, and single-chip microcomputer is connected with flash chip with two data reservoirs, capacitance-resistance resistance, crystal oscillator, encryption and deciphering module.
Further, said shell is provided with protective cover.
But the beneficial effect of the utility model encrypted U disk is: two data reservoirs that are provided with can strengthen storage volume; Can reach simultaneously the stored contents classification; Encryption that is provided with and deciphering module can ensure the security of stored contents; Flash chip adds enjoyment when but encrypted U disk is used, and improves aesthetics; It is bigger that it can reach storage volume, and stored contents can be classified, and is simple in structure, the purpose of good looking appearance.
Description of drawings
But Fig. 1 is the structural representation of the utility model encrypted U disk.
Embodiment
In the present embodiment; With reference to shown in Figure 1, but the utility model encrypted U disk comprises shell 1; And be arranged on the movement 2 in the shell 1; And be arranged on the USB interface 3 of shell 1 right-hand member, and said movement 2 is made up of pcb board 4, single-chip microcomputer 5, two data reservoirs 6, capacitance-resistance resistance 7, crystal oscillator 8, encryption and deciphering modules 11 and flash chip 9, and said USB interface 3 is connected with pcb board 4.
Wherein, Said single-chip microcomputer 5, two data reservoirs 6, capacitance-resistance resistance 7, crystal oscillator 8, encryption and deciphering modules 11 and flash chip 9 are welded on the pcb board 4, and single-chip microcomputer 5 is connected with flash chip 9 with two data reservoirs 6, capacitance-resistance resistance 7, crystal oscillator 8, encryption and deciphering module 11; Said shell 1 is provided with protective cover 10.
But the beneficial effect of the utility model encrypted U disk is: two data reservoirs that are provided with can strengthen storage volume; Can reach simultaneously the stored contents classification; Encryption that is provided with and deciphering module can ensure the security of stored contents; Flash chip adds enjoyment when but encrypted U disk is used, and improves aesthetics; It is bigger that it can reach storage volume, and stored contents can be classified, and is simple in structure, the purpose of good looking appearance.
The above is merely the embodiment of the utility model, but the protection domain of the utility model is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain that claims were limited.
