Personalized EigenTrust with the Beta Distribution精选.pdfVIP

Personalized EigenTrust with the Beta Distribution Daeseon Choi, Seunghun Jin, Younho Lee, and Yongsu Park This letter presents an enhancement of EigenTrust. Using the EigenTrust is a distributed protocol to compute the beta distribution, local trust values can be more correctly converged global trust values of peers by applying each peer’s evaluated. Simulation shows that the proposed scheme local trust value transitively. Unlike other models, EigenTrust calculates the local trust more correctly by up to 8%. For relies on linear algebraic theory to guarantee obtaining the personalization, the proposed scheme provides cumulative transitive values from the local trust to the global trust with converged global trust values. Moreover, it is very simple and mathematically guaranteed convergence. does not depend on complex parameters or assumptions. Recently, personalized schemes have appeared in which Keywords: Trust management, peer-to-peer network, social each peer organizes an initial trust group and gradually extends network, security, trust evaluation. the group and updates trust information [2]-[6] to provide personalized trust infor
