Abstract

The embodiment of the invention discloses an information transmission method and system. The method comprises the steps that a first communication node sends a first routing request to a second communication node through multiple paths, the second communication node determines n paths between the first communication node and the second communication node according to the first routing request, andsends routing responses to the first communication node through the n paths respectively, and the first communication node divides a target message into n sub-messages after receiving the n routing responses; the first communication node transmits the n sub-messages through the n paths by using a weighted threshold secret sharing algorithm, and each path transmits one sub-message; and the secondcommunication node receives M sub-messages through M paths in the n paths, and obtains the target message according to the M sub-messages and the weighted threshold secret sharing algorithm.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular to an information transmission method and system. Background technique [0002] With the continuous improvement of informatization level, satellite communication makes the transmission of information more convenient, and the reliability of satellite network is also high. However, information leakage or theft still exists in the process of information transmission. Information leakage will cause varying degrees of losses to individuals and companies, and have a great impact on people's lives and work. Contents of the invention [0003] The purpose of the embodiment of the present invention is to provide an information transmission method and system, so as to solve the problem of information leakage or theft in satellite communication, and improve the security of the network. [0004] In order to achieve the above purpose, the embodiment of the present inventio...
