Embodiment Construction

[0014] 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.

[0015] The secure communication method of the present invention mainly includes the following links at the information sending end:

[0016] 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...

Abstract

The invention discloses a secure communication method based on multichannel signal fragmentization transmission technology. The secure communication method comprises the following steps: dispersing communication data into small fragments in an information transmitting terminal, and then transmitting the small fragments by multiple information channels according to a certain rule; and receiving fragmentization data transmitted by the multiple channels in an information receiving terminal, and integrating the fragmentization data according to the fragmentization rule when the information is sent to obtain complete data transmitted by the transmitting terminal. The dispersion and integration rules of the fragments are determined by keys in the transmission process. By adoption of the secure communication method provided by the invention, on one hand, the difficulty of a third party to intercept complete information from the communication data can be greatly increased, so that the third party is difficult to crack signals via ultrahigh performance calculation; and on the other hand, even if enough information is intercepted by the multiple channels, complete effective data is difficult to be extracted from the encrypted fragmentization information, and it is difficult to recombine and recover the original data, therefore the security is improved.

Description

technical field [0001] 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 [0002] 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 s...
