This paper proposes privacy preserving authenticated access control scheme. In this scheme to scheme a user can create a file and store it securely in the cloud. This scheme consists of use of the two protocols Attribute Base Encryption (ABE) and Attribute Based Signature (ABS). Distributed access control of data stored in cloud so that only authorized users with valid attributes can access them. Authenticated users can store and modify their data on the cloud. The identity of the user is protected from the cloud during authentication. The access control and authentication are both collusion resistant, meaning that no two users can collude and access data or authenticate themselves, if they are individually not authorized. Revoked users cannot access data after they have been revoked. The proposed scheme is resilient to replay attacks. A writer whose attributes and keys have been revoked cannot write back stale information. The protocol supports multiple read and writes on the data stored in the cloud. The costs are comparable to the existing centralized approaches, and the expensive operations are mostly done by the cloud.
