基于用户间影响力度量的网络信任模型研究

为了解决完全依靠公钥证书体系为动态变化的网络环境提供信任支撑存在较大局限性的问题,需要在信任领域引入新技术。由于网络信任计算中的信任问题和社交网络中的用户影响力问题具有一定的相关性且属性认证、隐私交互等都是需要解决的问题,因此将用户影响力引入网络信任领域具有一定的可行性。基于上述理论,本文提出了一种基于用户间影响力的网络信任计算模型。首先,论述了模型的相关基础理论和模型构架;然后,研究其工作过程,分析设计信任算法;最后,将模型的各项性能与几种经典模型进行对比和测试并通过对模型参数对比的理论分析验证了模型的可行性、安全性和高效性等。

Research on Network Trust Model Based on Measurement of User's Influence

It is necessary to introduce new technology in the trust field due to the limitationin relying on the public key certificate system to provide the trust support for the dynamically changing network environment. Because the trust prob-lem in the network trust calculation has some relevance to the user influence in the social network and the attribute au-thentication and the privacy interaction are the problems thatneeded to be solved. Therefore, it is feasible to introduce the user influence into the network trust domain. Based on the above theory, a network trust computing model based on the influence of users is proposed. Firstly, the basic theory and model structure of the model are discussed. Then, the working process and design trust algorithm are analyzed. Finally, the performance of the model is compared with several classical models by experimental analyses and the feasibility, safety and efficiency of the model are verified by the theoretical analysis of the model parameters.
