Hybrid secure communication method for key data quantum encryption

Abstract

The invention discloses a hybrid secure communication method and system for key data quantum encryption and a storage medium, and the method comprises the steps: segmenting data in a communication service data stream according to different security levels through data analysis and discrimination or manual recognition and calibration; a quantum secret communication system in a'one-time pad 'working mode is used for transmitting data fragments calibrated as'security switching', a common communication system is used for transmitting other data fragments, and original communication service data flow is restored through fragment recombination. The hybrid secure communication method is compatible with other various technical schemes for improving the quantum secure communication rate from a physical layer, the rate pressure faced by the physical layer can be partially shared by an application layer, and meaningless calling of non-switching data on quantum keys is avoided through communication service data stream preprocessing. The maximum utilization of the quantum secure communication bandwidth is realized on the premise that key data has mathematically provable security, and an important support can be provided for a practical quantum secure communication network.

Description

technical field [0001] The invention belongs to the subject fields of quantum secure communication, computer network, data operation, etc., and specifically refers to a method of discriminating and calibrating the safety-concerned segments in the communication service data flow through data analysis, and using the ordinary communication system and the quantum secure communication system to transmit unmarked segments respectively. Fragments and calibration fragments, a hybrid secure communication technology that maximizes the use of quantum communication bandwidth, and particularly relates to a hybrid secure communication method, system and storage medium for quantum encryption of key data. Background technique [0002] Quantum communication is a communication technology that encodes information in quantum states. It can achieve information security interaction through the simultaneous sharing of quantum states by remote users: it depends on Heisenberg’s uncertainty principle,...

Problems solved by technology

However, the quantum key distribution rate (Kbps order) is usually much lower than the ordinary communication rate (Gbps order); although the quantum secure communication under the "one-time pad" working mode has mathematically provable security, it can only support the speed Lower data transmission services; low-speed quantum keys can be expanded into high-speed ordinary ciphers through mathematical complexity operations and support higher-speed data transmission services, but the security will degrade. The higher the expansion ratio, the security degradation the greater the degree
