Abstract
In order to improve the security and efficiency of data access control under multi-authority environment,this paper proposed a multi-authority and revocable access control in clouds (MARACC),which was an efficient data access control scheme for multi-authority in cloud storage systems.In MARACC,in order to eliminate the security risk introduced by central authority and collusion attack,different attributes authorities and DO generated the attribute-based secret key components respectively.Furthermore,it enabled user and attribute revocation respectively,which achieved fine-grained access control.Finally,it gave the security proof by using the decisional bilinear Diffie-Hellman (DBDH) assumption.The analysis and simulation results show that the proposed scheme is secure and efficient.关键词
