Chargeable quantum key and quantum secret communication network charging method and system

Abstract

The invention discloses a chargeable quantum key and a quantum secret communication network charging method and system. The method comprises the following steps: issuing corresponding quantum keys with currency values to a first user side and a second user side by using a quantum communication service station; charging for logging in the first quantum communication service station by the first user side and logging in the second quantum communication service station by the second user side is completed; completing charging of identity authentication between the first user side and the second user side; quantum secret communication of various services between the first user side and the second user side is realized; and performing post-auditing on the user side and the quantum communication service station by using the records of each quantum secret communication login and key negotiation. The method has the beneficial effects that the charging mode of the quantum key is relatively flexible; the charging mode of the quantum key in the invention is relatively simple, and the charging mode of the quantum key in the invention is relatively transparent.

Description

technical field [0001] The invention relates to the field of secure communication, in particular to a chargeable quantum key and a quantum secure communication network charging method and system. Background technique [0002] The trend of economic globalization has become unstoppable, with tens of billions of information flowing out on the Internet, just like humans have built a virtualized world in storage devices, where privacy and knowledge are concentrated. And this information has intangible value just like the resources in the real world. [0003] For individuals or organizations, to ensure that their information is not stolen, they must keep the keys in their own hands to ensure the security of their own information, which is crucial for key management. Traditional encryption methods mainly rely on asymmetric cryptosystems. The advantage of the asymmetric cryptosystem is that it does not require the process of agreeing a key between the two parties, which reduces a ...

AI Technical Summary

Problems solved by technology

[0007] 1. In the existing technology, the billing mode of the quantum key is not flexible enough: generally, the billing is performed according to the quantity of the quantum key when it is issued, and the billing of the communication initiator and the communication receiver is not distinguished;

[0008] 2. In the existing technology, the billing mode of the quantum key is relatively cumbersome: the use and billing of the quantum key are two independent processes and two independent operating systems;

[0009] 3. In the existing technology, the billing mode of the quantum key is not transparent enough: the user needs to obtain the billing details of each communication by querying
