【摘要】 随着P2P网络的广泛应用,基于P2P环境的信任模型也迅猛发展。但是目前提出的很多信任模型还远远不能令人满意。针对EigenRep全局信任模型所存在的网络性能开销过大的问题,提出了一种优化方法。仿真实验证明,这种优化方法在防御恶意攻击和降低网络性能开销两方面都可以取得理想的效果。更多还原

【Abstract】 With the extensive application of P2P network in the recent years,The trust model based-on P2P has become increasingly popular.However there are still some problems to be solved.Mainly aimed at the excessive cost of performance of EigenRep global trust model,an improved method is represented.The simulated results show that it is a notable effect in protecting from malicious attacks and reducing network cost of performance.更多还原
