Quantum network service station and quantum communication network

Abstract

The invention discloses a quantum network service station and a quantum communication network. The quantum network service station comprises a quantum service center used for forming a communication connection with each user side, and the quantum network service station is further provided with a true random number generator used for generating true random numbers; a user side key management server used for storing the true random numbers in the station and writing the true random numbers in a user specific device to form corresponding user side keys between the user side key management server and the user specific device, wherein the user side keys are separately applied to the encryption communication between the user sides and the quantum service center. According to the quantum network service station and the quantum communication network disclosed by the invention, the problem of access use and security of a quantum network terminal is solved by using a quantum key card.

Description

technical field [0001] The invention belongs to the field of quantum cryptography communication, in particular to a quantum network service station and a quantum communication network. Background technique [0002] The security of the quantum communication system is guaranteed by the Heisenberg uncertainty principle and the quantum non-cloning theorem in quantum mechanics, which makes the ever-increasing mathematical computing ability not threaten the security of the quantum cryptographic communication system, even in Quantum computers with powerful computing capabilities will appear in the future, and the quantum cryptography communication system will still be safe. At present, the point-to-point quantum communication system has been extensively researched, and already has a commercial basis, but from the perspective of practical application, multi-user access is a natural requirement, so it is inevitable that the quantum communication system will develop from point-to-poin...
