Research On Trust Mechanism Of Scientific Data Sharing Service Based On SLA

The scientific data sharing service discussed in this paper is based on cloud computing and based on the scientific data sharing service platform,and the service of scientific data storage,sharing,consultation and management is carried out to meet the needs of user scientific research.Because of the characteristics of resource virtualization and data complexity,it is difficult for scientific data sharing service providers to promise the users of scientific data sharing service their service capabilities and service quality,which affects the accuracy of scientific data sharing service selection and mutual trust between the parties.In addition,scientific data sharing service providers are more inclined to offer different levels of service management and charging.Service Level Agreement(SLA)means that the users of the Scientific Data Sharing Service and the service provider agree by agreement that both parties will have responsibilities and obligations in the actual scientific data sharing service.In view of the lack of trust of users in the process of receiving scientific data sharing services,based on the research framework of service level agreement(SLA),based on the theoretical research of scientific data sharing services and scientific data sharing service trust mechanism,a model of scientific data sharing service trust mechanism is constructed,and according to the problems of scientific data sharing service trust mechanism appeared in the simulation experiment,the optimization strategy of scientific data sharing service trust mechanism is put forward,with a view to further ensuring the security of users' privacy information.Maintain the trust relationship between scientific data sharing service providers and users of scientific data sharing services,encourage scientific data sharing service providers to improve their service level,promote the benign development of scientific data sharing services and the exchange and innovation of scientific activities,and provide reference for scientific data sharing service research.
