An attribute base encryption scheme for ciphertext policy for cloud storage

Liu, Yang

In the application environment of cloud storage, there are some problems, such as lack of fine-grained access control, difficulty in key management, and difficulty in resisting collusion attack, and a new ciphertext policy attribute base encryption for cloud storage (ciphertext-policy attribute-based encryption, Cp-abe) programme. By introducing the license attribute of the data master independent control, constructing the Cp-abe scheme of the different attribute domains can prevent the internal attack of the privileged users of the cloud storage system, so that the data owners can control the access of other shared users to their cloud data completely.
