Data Security In Clouds Using Decentralized Access Control, Anonymous Authentication And RSA Based Encryption

A new scheme for securing the data stored in clouds that supports anonymous authentication using a decentralized access control method is proposed. In the proposed scheme, the cloud verifies the authenticity of the series without knowing the user’s identity before storing data. Our scheme also has the added feature of RSA algorithm for encrypting data on cloud and access control in which only valid users are able to decrypt the stored information and deploying it to the cloud. The scheme prevents replay attacks and supports creation, modification, and reading data stored in the cloud and also addresses user revocation. Moreover, our authentication and access control scheme is decentralized unlike other access control schemes designed for clouds which are centralized. The communication, computation, and storage overheads are comparable to centralized approaches. Index Terms—Decentralized Access Control, KDC, RSA algorithm
