基于云计算层次架构的安全框架研究

摘要

Cloud computing security issues is the main problem of the cloud computing progress and a research focus of the IT field .T his paper firstly introduces the characteristics and service models of cloud computing .T hen it summarizes the cloud computing security issues .Finally according to the cloud computing level arckitectrure ,it discuss the securty policies to deal with the security promblems of each layer and puts forward a cloud computing security framework .%云计算安全问题是限制云计算发展的主要问题，一直是IT 界研究的热点。介绍了云计算的特点和服务模式，总结了云计算的安全问题，最后根据云计算的层次架构探讨了解决各层次安全问题的安全策略，并在此基础上提出了一种云计算安全框架。
