A Novel CP-ABE on Cloud Information Storage using CA & AA

Abstract

This scheme provides information owners more direct control on access policies. However, CP-ABE schemes to information access control for cloud storage systems are arduous because of the attribute revocation quandary. So This paper engender study on effective plus revocable information access control scheme for multi-ascendancy cloud storage systems, where there are multiple ascendant entities cooperate and each ascendancy is able to issue attributes independently. Concretely, this paper surveys a revocable multi-ascendancy CP-ABE scheme. The attribute revocation method can expeditiously accomplish some forward security and rearward security. This survey shows that revocable multi-ascendancy CP-ABE scheme is secure in the desultory oracle model and is more efficient than precedent multi-ascendancy CP-ABE.In a Cloud computing the information security achieved by Information Access Control Scheme. Cipher text-Policy Attribute-predicated Encryption is considered as one of the most felicitous scheme for information access control in cloud storage
