[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...
