Abstract

The invention discloses an information transmission encryption method based on combination of a national secret algorithm and a quantum communication technology. The method comprises the steps that: the encryption method is realized based on an optical communication network; a quantum key distribution device is arranged at the optical communication transmitting end; data transmitted by optical communication is subjected to quantum key encryption through the quantum key distribution device; furthermore, sender and receiver information of transmission information is subjected to national secretalgorithm encryption; sender address information decryption is carried out at first when a receiver decrypts the received information; and, a quantum key decryption channel is provided for transmission data decryption after sender information is decrypted. According to the method in the invention, transmission information encryption is carried out by adoption of the quantum key; the sender and thereceiver can perform secret communication; this is the first layer of encryption; furthermore, communication address information of the sender and the receiver is subjected to national secret algorithm encryption; stealing of local data after source data is tracked and the receiver receives information can be avoided; and thus, the secret information data transmission security is ensured better.

Description

technical field

[0001] The invention belongs to the field of communication technology, and in particular relates to a method for encrypting information transmission based on the combination of national secret algorithm and quantum communication technology. Background technique

[0002] Quantum communication technology is the product of the combination of quantum mechanics and traditional information science. At present, it mainly uses the quantum characteristics of light in the microscopic world to transmit digital information of "0" and "1" through single photons or entangled photons to achieve high-speed transmission of information. In theory, it can transmit large-capacity information, and can be used to develop codes that cannot be deciphered by classical means. However, due to the attenuation of photons during transmission, it is very difficult to realize long-distance optical fiber quantum secure communication in practical applications. At present, the maximum transmis...
