Problems solved by technology

In order to ensure the unconditional security of quantum cryptography network communication, it is necessary to encrypt routing signaling, which will consume a large amount of quantum keys and computing resources, thereby reducing network performance
If the routing signaling is not encrypted, it is difficult to ensure the legitimacy of the data encryption routing node, and the encrypted communication of the quantum cryptography network is vulnerable to the attack of the virtual routing node

Abstract

The invention discloses a data encryption routing method for a wide-area quantum cryptographic network, which comprises the following steps of grading a wide area network according to the number of contained metropolitan area networks, and selecting a data encryption routing path between an initial node and a destination node in a graded routing manner, therefore, the network delay is reduced, andthe management of routing nodes is facilitated.

Description

technical field [0001] The invention relates to the field of quantum communication, in particular to a wide-area quantum cryptography network data encryption routing method. Background technique [0002] Physically, quantum communication can be understood as high-performance communication realized by using quantum effects under the physical limit. In informatics, we believe that quantum communication is the use of the basic principles of quantum mechanics (such as the principle of non-cloning of quantum states and the measurement collapse properties of quantum states, etc.) or the use of quantum system-specific properties such as quantum state teleportation, as well as quantum measurement methods. To complete the information transfer between the two places. [0003] Quantum cryptography based on quantum key distribution (QKD) protocol is one of the most important practical applications of quantum communication at the present stage. Traditional cryptography is a cryptograph...
