A Hierarchical Access Control Technology for Cloud Storage

To protect data users stored on cloud platform, a new access control method that combines Oakley algorithm and a hierarchical scheme by privilege was proposed. CP-ABE algorithm, Oakley protocol and hierarchical management by privilege were integrated creatively to a new effective and secure access control model (OHB-model). The proposed scheme supported user dynamic topology changes. It could be used for hierarchical access control on cloud platform. Through the theoretical analysis and experimental verification, the security vulnerabilities could be solved effectively.
