Problems solved by technology

At present, the security of wired distribution of quantum keys depends on physical principles, and the distribution of quantum keys depends on the quantum backbone network, which requires high equipment requirements for the quantum key sending end and quantum key receiving end, and many quantum key networks need to be erected Equipment, high investment cost, complex project deployment
On the other hand, the security level of wirelessly distributing quantum keys is not high, because the seeds used to expand the generated keys mathematically are pseudo-random numbers

Abstract

The invention discloses a quantum key wireless-distribution method used for secure communication of terminal equipment. Seeds of distribution keys used for quantum key distribution are quantum true random numbers. The method comprises the following steps: (1) using a distribution key by a quantum key server to encrypt a quantum key, and sending an encrypted quantum key to terminal equipment through a manner of wireless transmission; and (2) receiving the encrypted quantum key, which is sent by the quantum key server, by the terminal equipment, using the same distribution key to decrypt the encrypted quantum key to obtain the quantum key distributed by the quantum key server. According to the quantum key wireless-distribution method of the invention, distribution of the quantum key and a quantum trunk network are separated, wireless transmission of the quantum key is completed with the only need for means of a traditional communication channel, project deployment is convenient and fast,input costs are low, and a distribution manner is simple; and on the other hand, the seeds used for extending the generated distribution keys are the quantum true random numbers, and security and a security level of wireless distribution of quantum keys can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of quantum communication, and in particular relates to a quantum key wireless distribution method for secure communication of terminal equipment, and a wireless quantum key distribution system for secure communication of terminal equipment. Background technique [0002] In recent years, traditional encryption methods based on mathematical principles have been proven to have security risks. This confirmation will strengthen people's concerns about the security of classical ciphers. At present, the mathematical cryptographic system that is widely used but has not been fully proved may be deciphered or found to have fatal security holes when people do not expect it. In addition, quantum computing also brings unprecedented potential threats to classical cryptosystems. Because of this, it is imperative to study cryptographic systems that can resist quantum computing attacks. All these factors promote the develop...
