Abstract
There exists some problems as the lack of fine-grained access control, low efficiency of key management and the vulnerability against collusion attack in the cloud storage environment, where there' s a large number of users and files. This paper proposed a new CP-ABE scheme applied in cloud storage. It introduced the permission attributes managed by the data owners, and constructed different attribute field to resolve the security problem such as the inner attacks and data control. Several experiments show that revocation method for user attributes performs wih high efficiency while providing security. In addition , it proves the scheme ig secure against the chosen-plaintext attack ( CPA) under the decision bilinear diffie hellman( DB-DH) assumption.关键词
