Abstract

The invention discloses a secure communication method based on multi-channel signal fragmentation transmission technology. At the information sending end, communication data is dispersed into small fragments, and then transmitted through multiple information channels according to certain rules; at the information receiving end, receiving The fragmented data transmitted by multiple channels is reintegrated according to the fragmented rules when the information is sent, so as to obtain the complete data sent by the sender. The rules of fragmentation and integration during transmission are determined by the key. The security method adopted in the present invention, on the one hand, can greatly increase the difficulty of communication data being intercepted by a third party to complete information, making it difficult to decipher the signal through ultra-high performance calculations; on the other hand, even if enough information is intercepted through multiple channels , It is also difficult to extract complete valid data from the encrypted fragmented information, and recombine and restore the original data, which improves the confidentiality.

Description

A secure communication method based on multi-channel signal fragmentation transmission technology

technical field

The invention relates to the field of secure communication, in particular to a secure communication method based on multi-channel signal fragmentation transmission technology. The invention can be used for encryption involving important information communications, such as enterprise secrets, military fields, etc., to prevent important information from being stolen by a third party.

Background technique

The current communication is based on one channel for information transmission. Whether it is wired communication or wireless communication, information is transmitted in one channel or on electromagnetic waves of the same band during the transmission process. The information is coherent and complete, and it is easy to be intercepted during transmission. Once stolen by a third party, all communication content will be leaked, which poses a great security risk. The present invention proposes a secure communication method based on multi-channel signal fragmentation transmission technology, that is, at the information sending end, the data to be sent each time is dispersed into many information fragments, and randomly dispersed into multiple channels according to a specific key At the information receiving end, through the control of the same key, the fragmented information is reintegrated into the original complete information. Since the communication information is scattered in multiple channels, and the signal fragments are randomly distributed in each channel, this increases the difficulty of intercepting information, even if the information data transmitted in multiple channels is intercepted, because the information is randomly scrambled It is difficult to integrate the fragments into complete original data, which increases the difficulty of intercepting complete information and prevents the communication content from being leaked.

Contents of the invention

The present invention provides an information fragmentation secure communication method based on multiple channel transmission, comprising the following steps: at the information sending end, a communication data is dispersed into a plurality of information fragments through a data processing module, and the plurality of information fragments are divided into Sending; at the information receiving end, through the data processing module, receive fragmented data transmitted by multiple channels, and reintegrate the received information fragments to restore the original data, and transmit the integrated data to the corresponding communication terminal.

According to a specific embodiment of the present invention, both the information sending end and the information receiving end have a data processing module, which are respectively used to complete the dispersion of the communication data and the reintegration of the information fragments.

According to a specific embodiment of the present invention, under the control of a control sequence, the data processing module at the sending end divides the data at the sending end into information fragments, and then disperses them into multiple information channels.

According to a specific embodiment of the present invention, the control sequence is generated according to a specific encryption key, and the fragmentation of information fragments and which information channels to select for transmission are determined by the encryption key.

According to a specific implementation manner of the present invention, the data processing module at the information receiving end receives information fragments sent from the sending end through multiple information channels.

According to a specific embodiment of the present invention, the data processing module at the information receiving end reintegrates the information fragments into complete original data under the control of a control sequence, and transmits the integrated data to the communication terminal.

According to a specific embodiment of the present invention, the control sequence at the receiving end is generated by a decryption key, and only when the decryption key is consistent with the encryption key at the information sending end, the decryption can be successful.

The present invention has the following advantages:

1) The data is decentralized, and it is sent and received through multiple information channels, preventing third parties from intercepting complete information and improving the security of information transmission;

2) The transmission data is scrambled and distributed to multiple information channels for communication according to a specific key. The selection of the number of information channels is determined by the key, so the data transmission has very good concealment and confidentiality, even if a third party is intercepting It is also difficult to recover the original communication data from information fragments transmitted by multiple information channels.

detailed description

The present invention provides an information fragmentation secure communication method based on multiple channel transmission, that is, each communication data is dispersed into information fragments at the information sending end, and the fragment information is controlled to be sent out through multiple information channels according to a specific key ; At the receiving end of the information, through the control of the same key, the fragmented information is received by the same number of information channels, and it is reassembled to restore the original communication data, and output to the communication terminal to complete a confidential communication.

The secure communication method of the present invention mainly includes the following links at the information sending end:

The sending end has a data processing module. When communicating, the sent data is changed from the original one-way information to multiple-way for information transmission;

In the data processing module, according to a specific key, the communication data is dispersed into data fragments, and then sent out through multiple information channels;

At the receiving end of the information, there is also a data processing module, which also has multiple data channels, which can receive multiplexed information fragments and integrate the data fragments;

In the data processing module at the receiving end, a specific key is used to integrate the scattered multi-channel data and restore it to one original data. The key used for decryption at the output end must be the same as the key used for encryption at the sending end.

The decrypted data is output to the communication terminal, thereby realizing a confidential communication.
