Quantum secret communication network charging method and system based on digital currency

Abstract

The invention discloses a quantum secret communication network charging method and system based on digital currency. The method comprises the following steps: S1, respectively issuing corresponding symmetric keys to a first user side and a second user side by using a pre-deployed quantum communication service station; s2, charging when the first user side logs in the first quantum communication service station and the second user side logs in the second quantum communication service station is realized by using a charging method; s3, charging of identity authentication between the first user side and the second user side is achieved through a charging method; and S4, quantum secret communication between the first user side and the second user side is realized by using a communication method. The beneficial effects are that digital currency transaction based on quantum secret communication can be realized, the quantum key card can be used as a digital currency wallet, two functions are combined into one piece of hardware, convenience is brought to a user, and in addition, the charging mode of the quantum key has the advantages of being simple, flexible and transparent.

Description

technical field [0001] The invention relates to the field of secure communication, in particular to a digital currency-based quantum secure communication network charging method and system. Background technique [0002] The core elements of the digital currency D-RMB system of the People's Bank of China are one currency, two types of libraries and three centers. A currency, namely "D-RMB" (DC / EP), referred to as D currency, specifically refers to a string of encrypted digital strings signed by the central bank representing a specific amount. Two types of libraries: D-RMB issuance library and bank library (central bank digital currency database, commercial bank digital currency database). In the issuance library, the digital currency is represented as the digital currency fund of the central bank; in the bank library, the digital currency is represented as the inventory digital cash of commercial banks. Three centers: one is the registration center (records the whole proces...

Problems solved by technology

[0005] 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; the user has not yet used the quantum key The key has already been billed, which may cause idle or even waste of quantum keys for users;

[0006] 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; there is a cash collection mode in the charging method, which is not convenient for follow-up audit;

[0007] 3. In the existing technology, the billing mode of the quantum key is not transparent enough: the user needs to query the billing details of each communication
