A networking design method for optical fiber quantum communication system

Abstract

The invention discloses a networking design and method of an optical fiber quantum communication system, including a site 1, a site 2, an encryption key and a decryption key, both sites 1 and 2 are data centers, site 1 is a data transmission center, and site 2 is the data receiving center, the encryption key is set at the lower end of site 1, quantum gateway A is set above the encryption key, quantum channel is set at the right end of quantum gateway A, quantum gateway B is set at the right end of quantum channel, and quantum gateway B is set at the lower end of the encryption key Security encryption router A, quantum security encryption router A has a VPN tunnel on the right end, quantum security encryption router B is on the right end of the VPN tunnel, an IP network is on the right end of the encryption key, a decryption key is on the right end of the IP network, quantum gateway B and quantum The secure encryption router B is connected to the decryption key, and the decryption key is connected to the site 2. The network design and method of the optical fiber quantum communication system are simple in structure, with a greatly improved communication rate, a significantly increased communication coverage, and at the same time reduced information Characterization of nonlinear effects in the transfer process.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a network design and method of an optical fiber quantum communication system. Background technique [0002] Information security has become an important consideration in the construction of communication networks of government, financial, military and other government and enterprise units. Quantum communication is expected to be the first to be applied in the construction of communication networks of such government and enterprise units due to its technical characteristics that are difficult to be eavesdropped. At present, quantum secure communication based on quantum key distribution has initially met the conditions for commercial use. With the gradual advancement and implementation of relevant technical standards, quantum secure communication networks will also be gradually rolled out. With the development of computer and communication technology, people's living standar...
