A LITERATURE SURVEY ON DECENTRALIZED ACCESS CONTROL WITH ANONYMOUS AUTHENTICATION OF DATA STORED IN CLOUDS USING KDC

This survey proposes a new decentralized access control scheme for secure data storage in clouds which supports anonymous authentication. The cloud verifies the authenticity of the series without significant knowledge in the user’s identity before storing information. This scheme also has the added feature of access control. In access control scheme only valid users are able to decrypt the stored data/information. This scheme prevents replay attacks also supports creation, modification, and reading information stored in the cloud. These schemes also address user revocation. Moreover, the authentication and access control scheme is decentralized and robust in nature unlike other access control schemes designed for clouds which are centralized. The computation, communication, and storage overheads are comparable to centralized approaches
