Research And Realization Of Trusted Scalar Anonymous Communication System In P2P Network

The Trusted Scalar Anonymous System combines Anonymous Communication technology with Trusted Scalar technology,brings the advantage of user's autonomy to anonymous communication system,has been a hot discussed issue in the academic field and anonymous application field.The research of TSAS in P2P Network is vital to the development of P2P anonymous communication.It not only gives the users the authority of autonomy,improves the convenience and practicability of the anonymous system,but also imports the system of Trusted Value.So it fulfills a trusted anonymous system,which privilege is equal to obligation.The main innovation and research in this paper includes the design and realization of Scalar Module and Trusted Value Module.In Scalar Module,it proposed a scalar anonymous communication idea,which is "high level,high anonymity,and high load".It also improved the Router Choice Strategy that is kemel in system,enlarged the capability and performance of system.The specific research included:the significance and need of scalar anonymous communication in P2P anonymous communication,the theories on how to realize scalar anonymity,the framework of the TSAS,the Router Choice Strategy based on anonymous rank,the research of the software figure of the TSAS,the realization of TSAS based on MFC and Socket,and the design scheme of bottom communicated user point.In Trusted Value Module,this paper proposed the idea of combining the scalar anonymity with trusted value system,designed a full series of trust value updating strategy based on the need of system,and designed a new updating formula that is "give different initiate trust value to different rank nodes,change the trust value during the communication process",which makes the system more reliable and flexible.The specific research of this module including:perfect and fulfill the amalgamation of the both modules,fulfill the software figure of the Trusted Value mechanism,which is "manage centrally,pass layered" based on the Broadcast and Socket technology,design and fulfill the dealing protocol in upper level points in the system.The test has verified that:the TSAS could fulfill the equilibrium of anonymity and all loads,satisfy the user's needs of autonomous selecting,and adapt the current and need of real application in P2P Network anonymous communication without break the original anonymity in P2P Network anonymous system.At the same time, the Trusted Value mechanism ameliorated the flexibility and reliability greatly.
