基于SLA的云计算动态信任评估模型
SLA-based dynamic trust evaluation for cloud computing
摘要
Abstract
How to effectively choose cloud service providers and sign service agreements with cloud providers is a difficult question.This paper proposes a SLA-based,dynamic,neutral,third-party trust evaluation system framework in cloud computing.By embedding monitoring agents at client-side and the cloud-side,real-time service information related to SLA can be observed and gathered.Combining users' subjective evaluation with these practical parameters and their changes,the system can compute and get the trust about cloud service providers' credibility comprehensively,dynamically.This paper presents the system frame structure,implementation rules of the trust evaluation,input and working process,etc.Compared with other trust evaluation methods,the method proposed in this paper combines a variety of subjective and objective evaluation sources,and provides the specific methods and processes.It also avoids the malicious interference effectively,and has better objectivity,accuracy and feasibility.关键词
