Research On Secure Computation Of Hybrid Identity Type And Its Distributed Simulation

Aiming at the realization of fairness in rational two-party computation, the concept of Error Value was introduced, and the rational secure two-party computation protocol was improved with the participants private type. From the perspective of game theory,the fairness of the rational secure two-party computation is how to promote cooperation between the parties and eventually reach equilibrium. Participants have private type refers to the identity of the participants have private.That is to say,they are either Tit-for-tat type or rational type. At the same time,in order to verify the validity of the protocols, the remote method invocation (RMI) technology was introduced to design a distributed integrated multi-agent platform solutions in this thesis. And JADE and Repast were selected to integrate as specific platform.The rational secure two-party computation protocol with the identity of the mixed type is fair, secure, robust, and so on. It can be applied in many important areas. Such as,the confidentiality computing intelligence exchange between multiple countries,developers to develop commercial area sign confidentiality contracts, electronic voting and electronic auction, etc.To solve above problems, related research work is described as follows:(1) We improved the rational secure two-party computation protocols with the participants have private type through introducing the concept of error value.Compared with the existing schemes, our scheme can achieved the Trembling Hand equilibrium and is much more stable.In this scheme,the utility function of the participants is based on the prisoner’s dilemma.In order to promote cooperation between the two participants, we add the utility punishment mechanism,and the error value of participants is associated directly with the utility of next round.(2) The remote method invocation(RMI) was used to realize distributed Jade and Repast integration platform,and the simulation experiment of the third chapter improved scheme was realized through this platform.After the simulation model is established after the simulation model is set up.Through analysing this model,the methods which are need to remote calls were listed, and the objects and methods were registered on the server side. Then the client called these methods remotely.It is convenient and fast just like calling local method.The experimental results show that the feasibility of distributed integration platform and the effectiveness of the participants have private type in rational secure two-party computation protocols.
