| 摘 要： | 在网格环境中,信任机制是解决网格服务安全问题的一种有效方法。研究了以P2P模式组织的网格服务资源之间的行为信任关系,提出了一个行为信任模型,研究了D-S证据理论和改进的证据冲突处理方法在行为信任模型中的应用,解决了模型中信任的度量、传递和组合问题。模拟实验与结果分析表明提出的行为信任模型具有合理性、有效性以及工程可行性。

| Abstract: | In grid environments,trust mechanisms are effective methods which can solve security problems of grid services.The paper studies behavior trust relations among grid services which are organized in the P2P pattern,presents a behavior trust model,and studies the application of D-S evidence theory and improved evidence conflict resolution policies in the behavior trust model.The paper solves trust metric,trust transfer and trust combination in the proposed behavior trust model.Simulations and result analyses show that the model is reasonable,effective and practical. |
