摘要
针对云计算中服务提供商存在未授权访问、用户外包数据泄露等安全问题,开展了云计算数据保护的研究,提出了一种基于数据等级分类的安全云计算方案。首先,分析目前云数据安全面临的主要挑战;其次,针对目前解决云数据安全方案中存在的问题,设计一种安全云方案,该方案通过设置不同安全级别数据降低保护数据所需的开销成本以及通过数据检索实现访问控制的安全;最后,仿真实验结果证明本方案的可靠性和有效性。
In view of the security problems in cloud computing,such as unauthorized access of service providers and leakage of outsourced data of users,the research on cloud computing data protection is carried out,and a secure cloud computing solution based on data hierarchy classification is proposed.Firstly,the main challenges of cloud data security are analyzed and summarized.Secondly,in view of the existing problems in cloud data security solutions,a security cloud solution is designed.This solution reduces the overhead cost of data protection by setting data of different security levels and achieves the security of access control through data retrieval.Finally,the simulation results show the reliability and effectiveness of the proposed scheme.
