Embodiment Construction

[0013] (1) Technical framework of a novel high-security optical link confidential communication method

[0014] The core idea of ​​the new high-security optical link confidential transmission method proposed by the present invention is to implement true randomization (one-time secret) split transmission on the data stream (encrypted by the self-synchronization sequence) transmitted by the link, and divide this True random bit stream encryption is organically combined with traditional serial cipher encryption. Randomize the link data stream (encrypted by the self-synchronization sequence) by outputting a constant quantum true random bit stream at the same rate as the link. This randomized stream mechanism conceals the All the format characteristics of the transmitted data stream, and due to the true randomness of the quantum random bit stream, the one-time pad true random stream encryption is realized; and then the security protection of the one-time pad true random code stream...

Description

technical field [0001] The invention relates to a novel high-safety optical link secret communication method based on random shunt encrypted transmission. Background technique [0002] At present, developed countries are competing to develop high-performance computing technologies, especially powerful new computing technologies such as quantum computing, neural network computing, and cloud computing. The link confidential communication transmission mode poses a huge security threat. [0003] In the existing wide-area secure communication network, the remote link connection is mainly realized by optical fiber transmission, and the optical fiber transmission link is not sensitive to the eavesdropping of optical signals, and it is easy for the opponent to eavesdrop halfway, so as to obtain the transmission code stream of the optical link The complete ciphertext information contained in it, and then advanced new high-performance computing technology is used to decipher and anal...
