摘　　要：为增强云计算环境中的安全性,提高云计算环境中的交易安全和可信程度,针对云计算环境的用户与云服务提供商的交易信任问题,提出了一种基于多Agent系统的三层架构云计算信任模型。模型针对云计算环境和多Agent系统的特点,提出了信任管理Agent、服务管理Agent和信任评估Agent三层架构,基于三层架构的信任管理模型,结合3种信任模式和根据历史交易记录的信任模型选择方法对云计算交易中的信任度进行判断。通过仿真实验证明,本文模型在多Agent交易情况和多Agent节点安全性的测试优于对比模型,并能在一定程度上减少云计算环境用户交易中的欺诈行为,减少用户损失,提高云环境下交易信任的安全程度。In order to improve the security in cloud computing environment and the reliability of transactions in cloud computing environment,a three-layer cloud computing trust model based on multi-Agent system to solve the transaction trust problem between users and cloud service providers is proposed in this paper.According to the characteristics of cloud computing environment and multi-Agent system,the model is composed of three layers of trust management Agent,service management Agent and trust evaluation Agent,with three layers of trust management model.It combines the three trust modes and the trust model selection method according to historical transaction records to judge the trust degree in cloud computing transactions.Simulation experiments prove that the model presented in this paper is superior to the other model in testing multi-Agent transactions and multi-Agent node security.The model presented in this paper can reduce fraudulent behaviors in user transactions in cloud computing environment to a certain extent,reduce user losses,and improve the security degree of transaction trust in cloud environment.
