发布时间：2021-03-16 05:22

　　In order to solve the problems of data sharing security and policy conflict in multicloud storage systems（MCSS）, this work designs an attribute mapping mechanism that extends ciphertext policy attribute-based encryption（CP-ABE）, and proposes a multi-authority CP-ABE access control model that satisfies the need for multicloud storage access control. The mapping mechanism mainly involves the tree structure of CP-ABE and provides support for the types of attribute values. The framework and workflow...
