A method and system for implementing secure billing in peer-to-peer network

[0107] Example 1

[0108] The implementation process of a secure charging method of the present invention is as follows: Figure 4 Shown. Specific steps are as follows:

[0109] 401) The resource user sends a request to the service control entity to request the use of a certain resource. This resource can be provided by other peer nodes. The request contains basic information such as the type, content, and service quality of the business.

[0110] 402) The business control entity selects resource provider A to provide services for this business. The business control entity allocates a business identifier for this business to identify this business. At the same time, the service control entity generates a service encryption feature code. The service encryption feature code can be randomly generated or generated by encryption of service-related information. After generating the service encryption feature code for this service, the service control entity generates the public part of t

[0126] The implementation process of another charging method of the present invention is as follows: Figure 5 Shown. Specific steps are as follows:

[0127] 501) The resource user sends a request to the service control entity to request the use of a certain resource. This resource can be provided by other peer nodes. The request contains basic information such as the type, content, and service quality of the business.

[0128] 502) The business control entity selects resource provider A to provide services for this business. The business control entity allocates a business identifier for this business to identify this business. At the same time, the service control entity generates multiple common parts of charging information. The common parts of multiple billing information can be targeted at different service qualities or provide longer billing time. For example, when the maximum billing duration of a single set of billing point cards is 60 minutes, four bil

[0136] The invention can support the situation that multiple resource users use the same resource. For example, resource provider A provides data relay functions for two resource users B and C. Specific steps are as follows:

[0137] 601) The resource user B initiates a request to the service control entity, requesting to connect to the resource user C through the relay service.

[0138] 602) The service control entity selects resource provider A to perform this relay service. The business control entity allocates a business identifier for this business to identify this business. At the same time, the service control entity generates a service encryption feature code and related charging point card and charging verification code for resource users B and C, respectively.

[0139] The service control entity sends a message to the resource provider A to request resource reservation. The request message contains the public part of service charging information, the char
