Abstract
The utility model discloses a novel encryption keyboard. The novel encryption keyboard comprises a main control unit circuit, a key input circuit and a state cryptographic algorithm encryption chip circuit, the main control unit circuit is respectively connected with and controlled by the key input circuit and the state cryptographic algorithm encryption chip circuit, the main control unit circuit is connected with the state cryptographic algorithm encryption chip circuit, the key circuit is replaced by a touch display screen, keys of the touch display screen can be ranked by the main control unit circuit so that outsiders can be prevented from speculating password by key directions, the encryption keyboard encrypts the password by a special encryption chip, then the encrypted password can be sent to pos in a serial communication interface circuit connecting mode, and convenience, universality and safety can be achieved.
Description
Technical field
The utility model relates to a kind of novel Encryption Keyboard.
Background technology
Existing Crypted password keyboard, inside does not adopt special encryption chip, just simply carries out random sequence for input password, and it is easily by being blocked and the password of interception being cracked.For general Encryption Keyboard, equally easily carried out the Brute Force of password by the external world in addition, there is various hidden danger in security therefore.
Summary of the invention
For above-mentioned technological deficiency, the utility model proposes a kind of novel Encryption Keyboard.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows:
A novel Encryption Keyboard, comprises main control unit circuit, button inputting circuits and encription algorithms approved by the State Password Administration Committee Office chip circuit, and described main control unit circuit is connected with described button inputting circuits and encription algorithms approved by the State Password Administration Committee Office chip circuit respectively and controlled by it.
Further, also comprise serial interface circuit, described serial interface circuit is connected with main control unit circuit and controlled by it.
Further, also comprise phonation circuit, described phonation circuit is connected with main control unit element circuit.
Further, also comprise self-destruction holding circuit, described self-destruction holding circuit is connected with main control unit circuit and controlled by it.
Further, described button inputting circuits is touch screen circuitry.
Further, described touch screen circuitry, according to the control of main control unit circuit, is carried out out of order list view by button order.
The beneficial effects of the utility model are; Encryption Keyboard of the present utility model, it has connected encription algorithms approved by the State Password Administration Committee Office chip circuit in main control unit circuit, its key circuit utilizes touch display screen to replace, thereby utilizes main control unit circuit to prevent that extraneous personnel from inferring password by button orientation to the button sequence of touch display screen; This Encryption Keyboard is encrypted password by special encryption chip, and the password after encrypting is sent to pos by the mode that then can connect by serial interface circuit, and it possesses convenience, versatility and security.In addition by design phonation circuit, can carry out operation indicating to user, improve the convenience using; in order to prevent the Brute Force of outer bound pair password; be provided with self-destruction holding circuit in inside, once there is above-mentioned situation, under the control of main control unit circuit, activate this circuit.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, a kind of novel Encryption Keyboard, comprise main control unit circuit, button inputting circuits and encription algorithms approved by the State Password Administration Committee Office chip circuit, described main control unit circuit is connected with described button inputting circuits and encription algorithms approved by the State Password Administration Committee Office chip circuit respectively and controlled by it, also comprise serial interface circuit, described serial interface circuit is connected with main control unit circuit and controlled by it, it has connected encription algorithms approved by the State Password Administration Committee Office chip circuit in main control unit circuit, its key circuit utilizes touch display screen to replace, thereby utilize main control unit circuit to prevent that extraneous personnel from inferring password by button orientation to the button sequence of touch display screen, this Encryption Keyboard is encrypted password by special encryption chip, and the password after encrypting is sent to pos by the mode that then can connect by serial interface circuit, and it possesses convenience, versatility and security.Preferably, also comprise phonation circuit, described phonation circuit is connected with main control unit element circuit, by design phonation circuit, can carry out operation indicating to user, improves the convenience using.In order to prevent the Brute Force of outer bound pair password, also comprise self-destruction holding circuit, described self-destruction holding circuit is connected with main control unit circuit and controlled by it.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, without departing from the concept of the premise utility; can also make some improvements and modifications, these improvements and modifications also should be considered as in the utility model protection domain.
