摘要
随着云计算的蓬勃发展,越来越多的企业和个人将他们的存储和计算需求付诸于云端.然而云计算的安全仍不容忽视,是当前的一个研究热点.对近年来云计算安全相关的研究成果进行总结,主要集中于数据安全,身份认证以及访问控制策略方面.也介绍了与可信计算技术相结合的云计算安全的相关研究框架和项目.根据这些研究成果,认为将可信计算与云计算思想相结合,建立"可信云计算"是未来云计算安全研究的一个重要方向.并且在最后提出了"可信云计算"发展的几个可能的研究主题.
More and more organizations and individuals outsource their storage and computing needs into a new economic and computing model,which is commonly referred to as cloud computing.As one of the hottest research issues,cloud computing security is also concerned by many scholars.This paper survey the recent advances in some security issues of cloud computing,which mainly focuses on the topics of data security,identity authentication and access control policy in cloud computing environment.It also introduces some enhancement frameworks and projects about the cloud security integrated with the Trusted Computing.According to these surveys,this paper believes that the combination between trusted computing and cloud computing will be a promising direction of the future cloud security researches,and proposes some interesting research issues in the end.
