Embodiment Construction

[0044] In order to further explain the technical means and functions adopted by the present invention to achieve the intended purpose, the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0045] In the first embodiment of the present invention, a quantum encryption communication method is proposed, such as figure 2 As shown, it is applied to the first quantum encryption communication device QCCD in the classical communication network CCN, and the method specifically includes the following steps:

[0046]Step S101: Send the key acquisition message carrying the key reading identifier to the first quantum key server QKS in the quantum key distribution network QKDN, so that the first QKS can pass the second QKS in the QKDN to the The key reading identifier and the key corresponding to the key reading identifier are sent to the second QCCD in the CCN.

[0047] Specifically, before step S101, the method ...

Abstract

The invention discloses a quantum encryption communication method and device and a computer readable storage medium. The method comprises the following steps of: obtaining a sample; sending the key acquisition message carrying the key reading identifier to a first quantum key server QKS in a quantum key distribution network QKDN, sending the key reading identifier and a key corresponding to the key reading identifier to a second QCCD in the CCN by the first QKS through a second QKS in the QKDN; receiving a secret key fed back by the first QKS, and sending the secret key reading identifier andthe communication session message encrypted by using the secret key to a second QCCD, so that the second QCCD searches the secret key corresponding to the secret key reading identifier, and decrypts the encrypted communication session message by using the searched secret key; Wherein the key reading identifier comprises a security parameter index SPI bit and an SPI round digit. The quantum encryption communication method and device solve the problem that in the existing quantum encryption communication process, an old session is frequently terminated, and a new session is generated.

Description

technical field [0001] The present invention relates to the technical field of quantum key communication, in particular to a quantum encryption communication method, equipment and computer-readable storage medium. Background technique [0002] China Telecom quantum encryption communication network system such as figure 1 Shown: where QKS (Quantum Key Server, quantum key server) is a component of QKDN (Quantum Key Distribution Network, quantum key distribution network), the main function is to provide quantum Key service; QCCD uses quantum keys to complete quantum encryption communication services through CCN (Classical Communication Network, classic communication network); the interface between QKS equipment and QCCD equipment is called QK_API (QuantumKey Application Interface, quantum key application interface) . Taking a typical network as an example, QKS is a PC server with a quantum key server program installed, and QKDN is a network connecting two QKS. QCCD is a rout...
