云存储服务由于数据管理和所有权分离,无法完全信任,导致数据隐私保护困难。为了保护云存储中不可信服务器上的数据隐私,提出了一种基于CP-ABE的无可信中心的云存储多授权访问控制方案--基于密文策略属性加密的非中心多授权代理重加密(NC-MACPABE)。NC-MACPABE优化了加权访问结构(WAS),允许对云存储系统中的同一文件进行不同级别的操作。引入身份染色的概念,进一步提高了用户的信息隐私性。该方案对重加密算法进行了改进,使数据所有者可以更灵活地撤销用户的访问权限。该方案被证明是安全的。实验结果还表明,去除中心权限可以解决有中心权限的多权限架构中存在的性能瓶颈,在大量用户同时申请访问云存储系统时,显著改善了用户体验。
The cloud storage service cannot be completely trusted because of the separation of data management and ownership, leading to the difficulty of data privacy protection. In order to protect the privacy of data on untrusted servers of cloud storage, a novel multi-authority access control scheme without a trustworthy central authority has been proposed based on CP-ABE for cloud storage systems, called non-centered multi-authority proxy re-encryption based on the cipher-text policy attribute-based encryption (NC-MACPABE). NC-MACPABE optimizes the weighted access structure (WAS) allowing different levels of operation on the same file in cloud storage system. The concept of identity dyeing is introduced to improve the users’ information privacy further. The re-encryption algorithm is improved in the scheme so that the data owner can revoke user’s access right in a more flexible way. The scheme is proved to be secure. And the experimental results also show that removing the central authority can resolve the existing performance bottleneck in the multi-authority architecture with a central authority, which significantly improves user experience when a large number of users apply for accesses to the cloud storage system at the same time.
