Problems solved by technology

The disadvantage of this method is: when the length of the additional tail information is less than the IP header option field and the length of the entire datagram is less than the maximum transmission unit MTU, the header option field can be used to carry the tail information without splitting the data packet

Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings.

[0043] refer to figure 1 , the steps that the present invention realizes are as follows:

[0044] Step 1, network configuration.

[0045] In the quantum communication network configuration, set the quantum communication terminal as the gateway of the local area network, and set the maximum segment size MSS of the transmission control protocol TCP message data part of the router's internal network port and external network port connected to the quantum communication terminal to 1448 byte.

[0046] combine figure 2 The classic application of the present invention accessing the quantum communication network is explained: figure 2 In , the dotted line represents the classical channel, and the solid line represents the quantum channel. The quantum communication terminal is equipped with two network cards, which are set as the gateway of the computer local area networ...

Abstract

The invention discloses a method for enabling a classical application to have access to a quantum communication network. The method includes the steps of (1) configuring the network, (2) receiving classical application data, (3) carrying out address conversion, (4) judging whether the data need to be sent to an outer network, (5) judging whether the data need to be encrypted, (6) judging whether the data are data packets, (7) encrypting a data portion, (8) judging whether decryption is needed, (9) decrypting the data portion, and (10) forwarding a network layer protocol IP datagram. According to the method, a quantum communication terminal is set to be an access gateway of an application terminal, classical application terminals are discriminated through IP addresses, a quantum encrypted datagram is identified with a head option field of the IP datagram, a starting portion of a secret key used for encrypting and decrypting is recorded, quantum encrypted transmission can be carried out on data of the quantum application terminal, meanwhile, data of the classical application terminals can be transmitted, and fusion of classical communication and quantum communication is achieved.

Description

technical field [0001] The invention belongs to the technical field of communication, and further relates to a method for accessing a quantum communication network for classical applications in the technical field of quantum communication network applications. In the present invention, the quantum communication terminal is set as the gateway of the quantum communication subnet, and by modifying the network address access protocol, the data of various applications can be encrypted and decrypted, so that quantum encryption can be used without detailed understanding of classical application protocols. key to realize the encrypted transmission of various application data. Background technique [0002] Quantum communication is based on Heisenberg's uncertainty principle and the non-cloning theorem of quantum states, which guarantee the unconditional security of quantum communication in terms of physical principles, so it has received extensive attention and achieved rapid develop...
