| 摘 要： | 服务资源的不可靠性使得用户难以安全有效的使用网络上的各种服务.参考社会学的人际关系信任模型,利用P2P网络建立基于信誉机制的服务发现模型,并利用Bayesian方法对服务节点的信誉度进行合理评估,从而设计出安全实用的服务发现算法.仿真结果证实,提出服务发现算法能够充分地利用P2P网络的高效性对可信的服务资源进行发现,促进服务节点间的交互,并能有效保障用户在可信方面的服务安全需求.

| Abstract: | The undependability of service resource affects the discovery of varies of service in the Internet.Referring to the trust relationship models of social people,we introduce a reputation mechanism based service resource discovery model with P2P network,and further propose a reasonable trust evaluate method with Bayes theory,and proposed the security and practical service discovery algorithm.Theoretical analysis and simulations prove that the service discovery algorithm can efficiently utilize P2P networks to discover trusted service resource,enhance collaborations of service nodes and guarantee user's need of trust on service security. |
