Abstract
The invention discloses a communication system and a communication method for the Internet transmission of chaotic security information. An independent server, receiving and transmitting terminals and built-in bidirectional key transmission modules are mutually connected together to form the system. In the method, a transmitter encrypts image text information via chaotic security, which is then uploaded to the independent server, the encrypted key is independently sent to a receiver via a public telephone line channel, and the receiver downloads the chaotically encrypted image text information and utilizes the received encrypted key to decrypt the image text information. The image text information transmission between the receiving and transmitting terminals of the invention utilizes the point-to-multipoint communication method performed by Internet media, so the image text information transmission does not pass a third party normally using the Email transmission method, thus greatly enhancing the security and independence of information transmission on the Internet. The independent server applies multiple security measures aiming at the ftp protocol, thus enhancing the theft-proof capability of information. The transmission of chaotically encrypted keys in an independent telephone channel ensures the anti-attack capability of the image text information.

Embodiment
Below in conjunction with drawings and Examples, the present invention is done detailed description further, but embodiments of the present invention are not limited to this.
As shown in Figure 1, the communication system of a kind of chaos safety information internet transmission of the present invention comprises separate server 1, receive/send out terminal (PC) 3-1,3-2,3-3 reaches to 3-N (N≤256, down together), built-in key two-way transport module 4-1,4-2,4-3 and constitute jointly to 4-N, each receives/sends out terminal (PC) 3-1,3-2,3-3 and be electrically connected mutually with separate server 1 by the Internet media netting twine 2 respectively to 3-N, and by holding wire and built-in key two-way transport module 4-1 separately, 4-2,4-3 and be electrically connected each built-in key two-way transport module 4-1 mutually to 4-N, 4-2,4-3 and be electrically connected mutually by the respective point of holding wire respectively to 4-N with public telephone line passage 5.
As shown in Figure 2; separate server is taked many maltilevel security precautionary measures, comprises that employing is greater than the restrict access authentication of 1024 User Defined tcp port address, the anti-bounce-back attack of forbidding the PORT order, the anti-deception in IP address, the thief-proof login password of one-time pad, the return code modification of user name protection.
As shown in Figure 3, the receipts of transmit leg/send out terminal (PC) to encrypt and the key transport process, comprise that the user imports key from keyboard, binding time information is formed key sequence, with key sequence graph text information is carried out chaos encryption, adds the key distinguishing mark in the facsimile file, graph text information is uploaded in login separate server, checking back, key sequence is exported, is sent into built-in key two-way transport module from serial port, and demanding party of the institute telephone number of transfering, connection telephone channel transmit key sequence automatically.
As shown in Figure 4, recipient's receipts/send out terminal (PC) to decipher and the key receiving course, the key sequence that comprises built-in key two-way transport module automatic reception provider, key sequence is sent into PC from serial port, login separate server, checking back pass graph text information down, relatively the key distinguishing mark in each facsimile file extracts the facsimile file that conforms to sign, utilizes key sequence to be decrypted.
Basic principle of the present invention: each receipts/send out terminal (PC) to connect into an independent communication system by grid line public media and separate server (PC), information transmission between each receipts/terminal (PC) all is core with the separate server, operate by the transfer of uploading and passing down of separate server and to realize, this communication mode then needn't have been guaranteed the safe independence of information by the third party of internet system.The host-host protocol of separate server has been taked the maltilevel security precautionary measures, to guarantee only to belong to the operation that legal receipts/terminal (PC) just can be carried out information uploading and be passed down in the native system; Wherein, employing greater than 1024 User Defined tcp port address, forbid the PORT order, because from 0 to 1023 tcp port number keeps the network service of doing usually, be easy to be subjected to proxy attack, so port address is arranged on high-order section and by User Defined, and forbid the PORT order, to increase difficulty of attacking; Take the restrict access measure, land the errors number of password input,, prevent IP address spoofing to close and being connected of user at the server end limited subscriber; Take popular one-time pad the password password, increase the difficulty of landing of password theft; The way that backspace sign indicating number in the server is made amendment is to make the assailant can't judge the true and false of user name, increases anti-follow-up control.Each built-in key two-way transport module adopts the art designs of two Chinese invention patent applications (publication number CN1540908A, CN1487694A) to form, wherein, be connected by the serial port of built-in serial communication interface with a receipts/terminal (PC), and be connected with telephone line channels by built-in phone lead-in, realize the transmission and the reception of key sequence jointly.The process that each receipts/send out terminal (PC) is uploaded graph text information to separate server is the user from the keyboard input of receiving/sending out terminal (PC) less than 1 constant as encryption key, from behind the decimal point 1 optional to 15, and combine with temporal information, formation has the key series of time tag, being used for that graph text information is carried out chaos encryption handles, add the key distinguishing mark to encrypting facsimile file, make numerous facsimile files of uploading can be corresponding with key sequence separately; Verification procedure by various regulations in the system lands separate server, and encrypt file is uploaded; Meanwhile, key sequence outputs to built-in key two-way transport module from serial port, puts through recipient's telephone number by built-in key two-way transport module, automatically keying sequence is sent from telephone line channels.Each receipts/send out terminal (PC) process of blit literary composition information under the separate server is, a called receipts/terminal (PC) is connected the telephone line channels of transmit leg automatically by built-in key two-way transport module, receive key sequence by telephone line channels, and send into receipts/send out terminal (PC) from serial port, the user of these a receipts/terminal (PC) lands separate server by the verification procedure of various regulations in the system, under pass encrypt file, key distinguishing mark and key sequence in the file are compared, the file that sign is conformed to carries out chaos decode with key sequence, restores original picture and text.
The inventor is through development test, think and realize that optimal way of the present invention can be: (1) is by shown in Figure 1, needs according to point-to-points communication mode are provided with receipts/terminal (PC) number, and each a receipts/terminal (PC) is electrically connected by grid line and separate server; By the built-in key two-way transport module of technology processing and fabricating of two Chinese invention patent applications (publication number CN1540908A, CN1487694A), be electrically connected mutually with a receipts/terminal (PC) and telephone line channels respectively with the telephone wire intake by serial line interface; Adopt the mixing mapping of Logistic and two kinds of broad research of Henon to carry out the chaos encryption processing of graph text information, adopt the C language to work out separate server (PC) respectively, receive/send out the handling procedure of terminal (PC) by the flow process shown in Fig. 2～4, debug accordingly and test, just can realize the present invention preferably.
