Abstract

The utility model provides a cipher machine, comprising the components as follows: an encrypting-decrypting module, which is used for parsing plaintext to generate ciphertext or parsing ciphertext to generate plaintext; a plaintext interface, which is used for inputting or outputting plaintext; a ciphertext interface, which is used for inputting or outputting ciphertext, wherein the ciphertext interface employs a serial port mode; and a power supply module for supplying power. The plaintext plaintext interface, the ciphertext interface and the power supply module are connected with the encrypting-decrypting module. According to the cipher machine, the ciphertext interface employs a serial port mode, the ciphertext generated after encryption processing by the cipher machine can only be decrypted by the cipher machine, under the precondition of a file encrypting-decrypting function, the operation process is recorded, man-machine interaction, remote monitor and remote operation functions are achieved, a servo file is automatically encrypted and decrypted, and the practical functions of the cipher machine are substantially expanded.

Description

A kind of cipher machine

Technical field

The utility model relates to a kind of encryption system, especially a kind of cipher machine.

Background technology

Existing secrecy system, is all that the user of file is authorized, such as the authority classification of website, password, U shield etc.Once hacker pretends to be validated user success, or legal secret key loses, or hacker directly crosses shielding harness and enter file system inside, and all files all can be read, be revised and copy.

Present secrecy system, basic ideas are all that check critical point is set on network path, in modes such as passwords, guarantee that incomer is legal.This protection is not the protection to file itself.Therefore,, once hacker enters file storage area, classified papers do not have own protective own.

Present secrecy system, its document storage mode, is all the document storage system under operating system.Identical storage mode, the success rate that makes illegal person attempt breaking through existing secrecy system greatly improves.

Present secrecy system, be all with computer interconnection under, the computing capability of computer, the work such as is encrypted.Computer also just must be subject to the monitoring of computer, and its ciphering process and password etc., do not have shielding to computer itself.Once computer is thoroughly monitored by hacker, by the system of computer information security, all do not have secret.

Present secrecy system, its trace mode or daily record of work etc. need the sufficiently high full-time staff of professional skill to be responsible for, or are exactly there is no trace mode, such as general U shield or secret USB flash disk, do not use record.

Utility model content

The purpose of this utility model is to provide a kind of cipher machine, realizing on the basis of file is encrypted/decipher function, also possessed the operating process of record, man-machine interaction, remote monitoring and remote operation, automatically the function to the be encrypted/decryption oprerations of servo file, has expanded the utility function of cipher machine greatly.

In order to achieve the above object, the utility model provides following technical scheme:

, comprising:

Encrypting-decrypting module forms ciphertext after expressly resolving, or forms expressly after ciphertext is resolved;

Plaintext interface, for input or output expressly;

Ciphertext interface, for input or the output of ciphertext, described ciphertext interface adopts serial ports pattern;

Power module, for providing power supply;

Described plaintext interface, ciphertext interface and power module are connected with encrypting-decrypting module respectively.

Further, described cipher machine also comprises logging modle, and described logging modle is connected with encrypting-decrypting module, for recording operating process, preserves operator's identity, operating time and the mode of operation to file.

Further, described cipher machine also comprises authorization module, for operator is confirmed.

Particularly, described authorization module can be one of mandate U shield, fingerprint recognition or identity card identification, or other can be owing to carrying out the mode of identification.

Further, described cipher machine also comprises human-computer interaction module, realizes operator with the man-machine interaction of cipher machine.

Particularly, described human-computer interaction module can be the modes such as indicator light and/or liquid crystal display screen.

Further, described cipher machine also comprises remote monitoring module, and described remote monitoring module is connected with encrypting-decrypting module, realizes real-time monitoring and remote operation to the mode of operation of encryption equipment.

Further, described cipher machine also comprises servo programe module, and described servo programe module is connected with encrypting-decrypting module, realizes automatically to the be encrypted/decryption oprerations of servo file, and operating process is carried out to record.

Further, described cipher machine can portable small-sized equipment, the form of hardware board exists.

The ciphertext interface of cipher machine of the present utility model adopts serial ports pattern, by the ciphertext after cipher machine encryption of the present utility model, must be decrypted by this cipher machine, realizing on the basis of file is encrypted/decipher function, possessed the operating process of record, man-machine interaction, remote monitoring and remote operation simultaneously, automatically the function to the be encrypted/decryption oprerations of servo file, has expanded the utility function of cipher machine greatly.

Cipher machine of the present utility model, the hardware encipher equipment that computer has independent current source and independent operation outward, the computing capability of computer not, also so be not subject to the monitoring of computer, its ciphering process and generating cipher etc., have strict shielding to computer itself, even if computer is thoroughly monitored by hacker, the file of encrypting by this cipher machine is still safe.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is the structural representation of cipher machine of the present utility model.

Embodiment

Below in conjunction with accompanying drawing of the present utility model, the technical solution of the utility model is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.

Shown in Fig. 1, a kind of cipher machine of the utility model, comprising:

Plaintext interface, for input or output expressly;

Power module, for providing power supply;

The ciphertext interface of cipher machine of the present utility model adopts serial ports pattern, by the ciphertext after cipher machine encryption of the present utility model, must be decrypted by this cipher machine, realized file is encrypted/is deciphered, and expressly, by after the input of plaintext interface, directly after encrypting-decrypting module is processed, by ciphertext interface, exported, in cipher machine, ciphertext is not stored, avoid plaintext and corresponding ciphertext to be stored in cipher machine simultaneously, thereby with chance, carried out cracking of ciphertext to malice effractor.
