摘　　要：云计算技术的发展加速了地理信息系统(GIS)的产业化进程,如何保证向云中用户提供的是安全、可信的GIS服务成为云GIS中重要的研究内容.为此,为了弥补单一远程证明者的不足之处,对远程证明机制进行了改进,提出了一种基于多Agent模型的远程证明通信机制,并将其用于云GIS中,通过将单一的验证者改造成多元的验证者集群,避免因单一验证者失效而带来的整体云GIS环境的安全失效.实验表明:在引入多Agent模型后,PaaS平台的远程证明过程将变的更加稳定安全,其相比于基于单一验证者的架构而言可用性更高.基于多重Agent的远程证明通信机制能够大大降低原有远程证明服务的不确定性,使远程证明能够时刻可用并且有效.Development of curyloud computing technology has accelerated the industrialization process of GIS(geographic information system),and how to ensure that cloud provides secure,trusted GIS services to user in cloud becomes research focus.Remote attestation communication mechanism was improved,and an attestation scheme based on multiple attesters was proposed and applied in cloud GIS,which avoided the invalidity caused by the disability of the unique attester in the cloud GIS environment.Experiments show that remote attestation process of PaaS platform becomes more stable and secure,which has higher availability compared to those based on a single authentication framework after introduction of multi-agent model.Multi-agent-based remote attestation communication mechanism can greatly reduce the existing uncertainty of remote attestation services,and make remote time available and effective.
