Embodiment Construction

[0024] Quantum key distribution, based on the basic principles of quantum mechanics, unconditionally securely distributes keys between two directly connected points. Taking the most classic BB84 protocol as an example, the protocol shares 4 quantum states to form two sets of orthogonal bases, and each set of orthogonal bases is also a set of measurement bases. The correct result can only be obtained by using the same group of measurement basis to measure the quantum state. The specific communication process is as follows: the sender of the key randomly selects one of the four quantum states, and sends it to the receiver through the quantum channel, the receiver randomly selects a measurement base to measure, and obtains a result, both parties record their own The selection and measurement results are compared with each other through classical channels, and the results of those wrongly selected measurement bases are deleted. If necessary, the final key can be established betwe...

Abstract

The invention discloses a quantum key distribution system for safety communication of an electric vehicle intelligent charging network. The quantum key distribution is realized on the basis of a hierarchy KDC (Key Distribution Centre) mode. The distribution of the quantum key distribution system is performed by a key distribution unit. The key distribution unit comprises a key management module (1) and a key management module (2) of a charging station. The key management module (1) is positioned in an operation management center. Communication and transmission of data and commands are performed between the key management module (1) and the key management module (2) reciprocally via classic channels. Keys are provided for the key management module (2) by the key management module (1) via quantum channels. According to the quantum key distribution system for safety communication of the electric vehicle intelligent charging network, disclosed by the invention, unconditional safety communication of the data is realized, and stability and safety of the network operation are guaranteed.

Description

technical field [0001] The invention relates to the field of secure communication in electric power systems, in particular to a quantum key distribution system for secure communication in an electric vehicle intelligent charging network. Background technique [0002] In recent years, the energy crisis caused by the consumption of petroleum resources and the air pollution caused by traditional fuel vehicles have driven people to develop more environmentally friendly vehicles. As a green vehicle with broad development prospects, electric vehicles can solve energy and environmental problems to a certain extent, and become one of the hot spots in the development of the automotive world today. [0003] In order to realize the commercialization of electric vehicles, necessary service supporting infrastructure such as electric vehicle charging stations must be set up. In order to meet the needs of users, the coverage of charging stations will inevitably increase with the increase ...
