Public scene anonymous communication billing system and method based on billing digital certificate

Abstract

The invention discloses a public scene anonymous communication billing system and method based on a billing digital certificate, and the billing mode of public scene service is simple: the use and billing of the public scene service are unified into an independent process and a set of independent operation system, and are convenient to develop, use and maintain; the charging mode of the public scene service is relatively transparent; a user does not need to obtain charging details of each communication through query; according to the invention, the digital certificate is bound with the corresponding value, and the user uses the digital certificate to consume the corresponding value, so that the user can clearly know the specific charging condition of each communication, and the user can locally store each transaction record without querying charging details in a service party. According to the method, the risk of user information leakage does not exist in the public scene service, quantum computing can be resisted, the identity of the user using the public scene service every time is anonymous and different, and user privacy cannot be collected and illegally used.

Description

technical field [0001] The invention relates to the communication field, in particular to a system and method for anonymous communication charging in public scenarios based on chargeable digital certificates. Background technique [0002] CA (CertificationAuthority) is the certificate issuing authority, which is the core of Public Key Infrastructure (PKI). CA is the authority responsible for issuing certificates, authenticating certificates, and managing issued certificates. The CA has a certificate (containing the CA public key). Public users on the Internet trust the CA by verifying the signature of the CA, and anyone can get the certificate of the CA to verify the certificate issued by it. The format and verification method of the certificate generally follow the X.509 international standard. [0003] A digital signature, also known as a public key digital signature, is a digital string that only the sender of the information can generate and cannot be forged by others...

AI Technical Summary

Problems solved by technology

[0006] 1. The billing mode of the public scene service in the prior art is relatively cumbersome, and the use and billing of the public scene service are two independent processes and two independent operating systems;

[0007] 2. The billing mode of the public scene service in the prior art is not transparent enough, and the user needs to obtain the billing details of each public scene service through query;

[0008] 3. The information transmission in the public scene service in the existing technology is not resistant to quantum computing, and there is a risk of user information leakage. The user's identity information is exposed on the network, which may easily lead to the collection and illegal use of user privacy information
