基于双方承诺的云环境服务信任管理机制

Trust management mechanism of cloud environment service based on two side commitment

用户与云服务提供商间的信任影响着云计算的普及和发展。针对当前用户与云服务提供商的不信任问题,该文构建了基于双方承诺的云环境服务信任管理机制。该机制对服务提供商所提供的服务质量进行在线监测,然后根据双方承诺的服务等级协议对服务提供商的可信度进行评估,建立用户和服务提供商间的信任。最后在Matlab 2014平台上对该机制的有效性进行仿真验证。结果表明,该文云环境服务信任管理机制可以客观合理地评估服务提供商的可信度,帮助用户准确选择可信度高的云服务提供商。

Trust between users and cloud service providers affects popularity and development of cloud computing. In view of the untruth problem between the user and the cloud service provider,a novel trust management mechanism of cloud environment service based on the two sides commitment is constructed in this paper. Firstly,the quality of service provided by service providers is monitored online,and then the credibility of the service provider is evaluated according to the service level agreement of two sides commitment to establish trust between users and service providers. The simulation experiment is carried out on the Matlab 2014 platform to verify the effectiveness of the mechanism. The results show that the proposed mechanism can evaluate the credibility of the service provider objectively and reasonably and can help users elect high credibility cloud service providers accurately,so it has certain practical application value.
