Embodiment Construction

[0036] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are provided by way of illustration in order to fully convey the spirit of the present invention to those skilled in the art to which the present invention pertains. Therefore, the present invention is not limited to the embodiments disclosed herein.

[0037]Through the analysis of the working process of the quantum cryptography network, the applicant found through research that the relay key data packets that need to be encrypted in the encrypted communication usually arrive at each network node in groups, which is a completely random and the arrival time interval is exponential. The distributed process constitutes a Poisson process, therefore, the Poisson distribution probability model can be used to accurately express the requirement of the key relay process in the quantum cryptography network for the amount of...

Abstract

The present invention proposes a quantum cryptography network key generation control method, which is based on the network demand experience value related to the existing amount of synchronized quantum key in the network node, the consumption demand of the quantum key, and the demand for network resources. The Poisson distribution probability model is used to provide more accurate quantum key generation control for quantum cryptography networks.

Description

technical field [0001] The invention relates to the field of quantum cryptography communication, in particular to a quantum cryptography network key generation control method based on a Poisson distribution probability model. Background technique [0002] Quantum communication is a new interdisciplinary subject developed in the past two decades, and a new research field combining quantum theory and information theory. Recently, this subject has gradually moved from theory to experiment, and to practical development. Efficient and secure information transmission has attracted increasing attention. [0003] In physics, 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...
