摘要：为了保护混合云存储中公有云端数据的安全,尤其是数据访问隐私,提出了一个混合云存储方案。在企业私有云环境中对数据进行加密、合并、分割等处理,将文件元数据存放于组织内部的数据库中,将处理后的数据存放于公共云存储空间,实现数据内容和元数据的分离,提高公有云端数据的安全性和数据访问的隐私性。根据原型系统获得的实验结果表明了该方案在数据访问隐私保护中的作用。
To protect the security and privacy of access of out-sourced data,a hybrid cloud storage system was proposed to solve these problems.The system process data were stored out-sourced by using encryption,combination and fragment.The metadata of original data files were stored in local devices and the processed data were upload to public cloud storage.In this way,the safe and private access of original data was guaranteed by separating processed data and metadata.According to the result of experi-ment on the system prototype,the validity of proposed scheme was demonstrated.
