Abstract

A mobile hard disk with a hardware encryption function and a data security protection function in integrated mode comprises a hard disk, a hard disk data encryption and conversion controller, a password input setting controller, a touch type key controller and keys. The hard disk data encryption and conversion controller is connected with a computer communication interface, is connected with the hard disk through a serial advanced technology attachment (SATA) interface, and is connected with the password input setting controller through a serial peripheral interface (SPI) at the same time, and the keys are connected with the touch type key controller. According to the mobile hard disk with the hardware encryption function and the data security protection function in integrated mode, a hardware encryption method is utilized, multiple types of data transmission interfaces for communication with a computer are utilized, the interfaces are directly connected to a circuit of the mobile hard disk, a user does not need to install any encryption software, and no system compatibility problem exists. After the hard disk is encrypted, even if the hard disk is dismantled, data cannot be read or seen by means of any other devices, the data can only be read on the hard disk through password decryption, and therefore security of encrypted data is greatly improved.

Description

The portable hard drive of integrated hardware encryption and data security protecting

Technical field

The utility model relates to electronic circuit, particularly a kind of Circuits System of fixed disk data enciphering.

Technical background

Along with popularizing fast of computer, a large amount of data in the usual use of computer, can occur and need storage, portable hard drive is widely used under this application prospect as a kind of light and storage facilities high power capacity, traditional portable hard drive does not cause data stolen owing to do not possess data encryption feature easily, data is lost rear the utilization by the people of bad intentions and economic loss and personal injury also engender in people's routine use based on ciphering type portable hard drive under this background.Main ciphering type portable hard drive all is to adopt software cryptography or hardware encipher in the market, needs on computers mounting software and by computer input password, use procedure more complicated and user lose password easily.

The utility model content

Technical problem to be solved in the utility model provides the Novel hard disk system that a kind of software cryptography mode that does not need to use installation is encrypted, itself and hard disk combination of hardware make encrypt safer.

The portable hard drive of a kind of integrated hardware encryption and data security protecting; comprise that hard disk, fixed disk data enciphering and data-switching controller, Password Input arrange controller, touch-key controller and button; described fixed disk data enciphering and data-switching controller are connected with the dataphone interface; be connected, with described Password Input controller be set and be connected by the SPI interface by the SATA interface with described hard disk respectively simultaneously, described button is connected with the touch-key controller.

Further, described fixed disk data enciphering and data-switching controller comprise USB, 1394, SATA and PATA data transmission interface.

This novel beneficial effect is: adopt hardware encipher, use multiple and data transmission interface dataphone: USB2.0/USB3.0/1394/ESATA, owing to directly be connected with the portable hard drive circuit, the user does not need to install any encryption software, and there is not the problem of system compatibility in this system yet.Even be removed other any equipment of use through the hard disk of encrypting, its data also can't be read and data invisible, data only on this equipment by just reading behind the password to decipher, greatly strengthened the data security of encrypting.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described:

As shown in Figure 1; the portable hard drive of a kind of integrated hardware encryption and data security protecting; comprise hard disk; fixed disk data enciphering and data-switching controller; Password Input arranges controller; touch-key controller and button; described fixed disk data enciphering and data-switching controller are connected with the dataphone interface; be connected by the SATA interface with described hard disk respectively simultaneously; with described Password Input controller being set is connected by the SPI interface; described button is connected with the touch-key controller; needing hard disk to be encrypted and to decipher rear hard disc data by the input of the touch keyboard on portable hard drive password in the use procedure could use; the computer use be can connect flexibly and any software, plug and play do not needed to install.

Further, described fixed disk data enciphering and data-switching controller comprise USB, 1394, SATA and PATA data transmission interface, can support several data transmission mode and the communication of dataphone interactive interfacing.

Described Password Input arranges controller and also is connected with LCD display, can indicate operation indicating.Fixed disk data enciphering and data-switching controller, Password Input arrange controller and are connected with respectively the led state pilot lamp, and the state in encryption, the decrypting process is indicated.

Below further above-mentioned each interface and controller are narrated, such as Fig. 2, Fig. 3, Fig. 4 and Fig. 9, shown in Figure 10, described fixed disk data enciphering and data-switching controller are connected with LED light LED-R and LED-G, to be in encrypted state or to be in decrypted state in order to indicate hard disk, the led circuit that shows simultaneously encrypted state also comprises a hummer SP1, and it also comprises USB interface connecting circuit modules A and SATA interface link block B; Further, Fig. 9,10 with Fig. 2 in control chip respective pin GPIO17, GPIO18, GPIO19 link to each other with cue circuit, hummer links to each other with the GPIO19 pin.Fig. 5,6 has represented the connected circuit of a plurality of sensors that the touch-key controller is corresponding, and except LCD display connected, main control chip was also with the control button and the circuit connection of the corresponding instruction of button is set among Fig. 7.
