摘要：A new decentralized access control scheme for secure data storage in clouds, which supports anonymousauthentication. Access control is processed on decentralized KDCs it is being more secure for data encryption.Generated decentralized KDC's are then grouped by (KGC). In our scheme, the cloud verifies the authenticity of theuser without knowing the user’s identity before storing the data. This has the added feature of access control in whichonly valid users are able to decrypt the stored information. Our scheme prevents replay attacks and supports creation,modification and reading data stored in the cloud. And also addresses user revocation. It is a decentralized, robust andaccess control schemes designed for cloud. The communication, computation, and storage overheads are comparable tocentralized approaches.
