Description
Technical field
The present invention relates to secret instant messaging field, particularly relate to the secret instant messaging mechanism based on many software fragmentation transmission technology.The present invention can be used for the safe and secret instant messaging realizing between two methods terminal by conventional software and public network, effectively reduces by the risk of assault.
Background technology
Current instant communication software, as QQ, micro-letter, homing pigeon, MSN etc., be widely used, and function becomes increasingly abundant perfect.But, providing convenient for people's life and while amusement, instant communication software also exist by assault, the potential safety hazard such as monitored, Content of Communication security performance deficiency.Such as, attack once software server meets with, the communications records of all users all can be stolen.
Summary of the invention
In view of this, the invention provides a kind of instant messaging mechanism avoiding information to be stolen, namely at transmitting terminal, the data scatter of communication is become fractionlet, then sent by multiple software according to certain rule; At receiving terminal, multiple software accepts data, is then integrated by data fragment, obtains complete data.Each transmission, the software category of selection and number can adjust flexibly, are determined, and for specific one software, only bear a part of transformation task, be mess code, thus can effectively avoid information to be stolen inside communications records by key.
According to an aspect of the present invention, which provide a kind of secret communication method based on multiple application fragmentsization transmission, it comprises:
Step 1, information transmitting terminal produce application data to be sent;
Step 2, utilize encryption key that described application data to be sent is resolved into multiple application data fragment;
Step 3, described multiple application data fragment to be sent by multiple application passage;
Step 4, information receiving end receive described multiple application data fragment respectively by corresponding multiple application passage;
Step 5, utilize decruption key that described multiple application data segments return is become a circuit-switched data.
According to a further aspect of the invention, which provide a kind of secure communication device based on multiple application fragmentsization transmission, it comprises:
Data generating module, produces application data to be sent;
Encrypting module, utilizes encryption key that described application data to be sent is resolved into multiple application data fragment;
Sending module, is sent described multiple application data fragment by multiple application passage;
Data reception module, receives described multiple application data fragment respectively by corresponding multiple application passage;
Deciphering module, utilizes decruption key that described multiple application data segments return is become a circuit-switched data.
The present invention has the following advantages:
1). the Internet instant communication software by multiple routine realizes the special instant communication function of maintaining secrecy, and implementation procedure is simple;
2). by the multiple point-to-point data channel of multipair software building, the information of transmission divided after fragmentating, be dispersed in disorderly in multiple data channel and transmit, data hiding is good.
Accompanying drawing explanation
Fig. 1 is the implementation procedure schematic block diagram of secret communication method in the present invention.
Embodiment
For making the object, technical solutions and advantages of the present invention clearly understand, below in conjunction with specific embodiment, and with reference to accompanying drawing, the present invention is described in further detail.
The invention discloses a kind of secret communication method based on multiple application fragments transmission technology, it comprises:
Step 1, information transmitting terminal produce application data to be sent;
Step 2, utilize encryption key that described application data to be sent is resolved into multiple application data fragment;
Step 3, described multiple application data fragment to be sent by multiple application passage;
Step 4, information receiving end receive described multiple application data fragment respectively by corresponding multiple application passage;
Step 5, utilize decruption key that described multiple application data segments return is become a circuit-switched data.
Alternatively, described multiple application passage is multiple instant messaging application software; The application data to be sent that information transmitting terminal produces is produced by the one in described multiple instant messaging application software, or other application software being different from described multiple instant messaging application software produced.
Alternatively, described multiple instant messaging application software is the part or all of application software in predetermined instant messaging application software set, and each send the multiple instant messaging application software that application data uses number and kind can be identical or different, determined by encryption key.
Alternatively, described decruption key is identical with encryption key.
The dispersion of the software category used in transmitting procedure in the present invention, number and fragment is all determined by key with the rule integrated.
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Information transmit-receive both sides have an instant messaging interface, this interface is similar to conventional instant communication software interface, the operation interface of the functions such as word actual conversation, file transfer, voice and video real time communication is provided, has a data outlet and a Data entries.
The encryption and decryption of the complete paired data of the data processing module in Fig. 1.This module is connected with instant messaging interface, is connected again with each software in IM group.At data encryption end, this module receives comes from the data at instant messaging interface, then according to specific key, after data are divided into fractionlet, be distributed to multiple data channel, each data channel transfers data to an instant communication software, and the number of selector channel and kind are also determined by the information comprised in password, such as select QQ and passage corresponding to micro-letter two softwares specifically, next time selects the passage that QQ, homing pigeon and MSN tri-softwares are corresponding; At data deciphering end, this module accepts the multichannel data fragment from multiple software, performs deciphering, data fragment is reintegrated into an original circuit-switched data, and the circuit-switched data recovered is transferred to instant messaging interface according to double secret key data.Only have when receiving terminal decipher the key used and transmitting terminal encrypt the key used the same time, could successful decryption.
IM group's module in figure is a group be made up of multiple instant communication software, such as QQ, micro-letter, homing pigeon, MSN etc., and each software is connected with data processing module, and by being connected with the Internet, realizes its normal function.
Public network in figure is Internet, each instant communication software realizes point-to-point instant communication function by the server be connected in the Internet, the information of the QQ software transmission of such as transmitting terminal arrives the QQ software of receiving terminal exactly, constructs a circuit-switched data passage.
