Ciphertext policy attribute based encryption scheme for cloud storage
云存储的应用环境中存在缺乏细粒度访问控制、密钥管理难度大、难以抵御合谋攻击等问题,为此提出了一种新的用于云存储的密文策略属性基加密(ciphertext-policy attribute-based encryption,CP-ABE)方案.通过引入由数据属主独立控制的许可属性,构建不同属性域的CP-ABE方案,能够防止云存储系统特权用户的内部攻击,使数据属主能完全控制其他共享用户对其云数据的访问.实验结果表明,该方案在提供安全性的同时能极大地提…查看全部>>
There exists some problems as the lack of fine-grained access control, low efficiency of key management and the vulnerability against collusion attack in the cloud storage environment, where there' s a large number of users and files. This paper proposed a new CP-ABE scheme applied in cloud storage. It introduced the permission attributes managed by the data owners, and constructed different attribute field to resolve the security problem such as the inner a…查看全部>>
