摘要
用户数据在公有云计算环境中的存储位置是用户无法有效控制的,这样就给用户数据的安全造成了较大的威胁.为了保护云计算中用户核心数据的安全,提出了采用混合云架构保护用户数据安全的思想,为此设计了基于云计算的用户核心数据保护模型,将用户的数据分解成核心数据和一般数据,核心数据将存储在用户可控的私有云中,一般数据经过过滤后存储在服务商的公有云中,有效地解决了用户核心数据的保护和安全问题.通过利用已有的网络安全产品,并结合所设计的数据分类算法,按模型构建了基于云计算的企业核心数据保护系统,经过实际使用验证了模型的有效性,为云计算中用户核心数据的保护探索了新的方法.
Users aren't able to effectively obtain control of the storage position of their own data in the public cloud, which considerably threatens the security of users' data. In order to protect the users' core data in cloud com puting, we proposed that we could protect users; data with the hybrid cloud architecture, thus we designed the Users' Core Data Protection Model Based on Cloud Computing, UCDPMBCC. This model divides users' data into two parts, the core data and the general data. The core data would be stored in private cloud which users can control, while the general data would be stored in the public cloud from the service provider after being filtered. This effectively solves the protection and security problem of users' core data. By taking advantage of the existing internet security products, we constructed the Users' Core Data Protection Model Based on Cloud Computing according to the model together with the algorithm for data sorting designed by us. The effectiveness of the model has been testified with actual use and it explores a new approach to provide the users with the protection for their core data.
