Abstract

The confidentiality and usability of sensitive data in outsourcing processes are particularly important in open systems. When the user's attribute is revoked or restored in the CP-ABE system, the flexibility of the dynamic change of the corresponding strategy is a challenge. In the paper, we presents a CP-ABE access control scheme which supports the dynamic changes of policy attribute. We expanded its Access Structure Tree, established a full policy access control mechanism that supports the minimum shared re-encryption key attribute set, and realized the change of the flexible access policy in the scheme.
