“…For instance, Ciphertext-Policy Attributebased Encryption (CP-ABE) requires a trusted authority that manages all the attributes and distributes keys in the system and cannot be directly applied to data access control for multiauthority cloud storage systems, due to the inefficiency of decryption and revocation. To address these problems Yang et al [20] propose DAC-MACS (Data Access Control for MultiAuthority Cloud Storage), an effective and secure data access control scheme with efficient decryption and revocation. In this scheme, a new multi-authority CP-ABE scheme with efficient decryption is built.…”

In recent years, cloud computing is highly embraced and considered a must have in the IT world. Cloud computing is a computing paradigm, where a large pool of systems are connected in private, public or hybrid networks, to provide dynamically scalable infrastructure for computing resources. One of the services provided by cloud computing is cloud storage that enables the upload and the retrieval of different kinds of data. Accessing cloud storage service through Internet and pay as you used subscription have been the reasons for the emergence of methods and techniques to effectively store data and reduce storage security vulnerabilities in the cloud storage. This paper provides a survey of some proposed cloud storage methods and techniques, their advantages and drawbacks and makes stress on the current requirements for storage techniques in cloud computing.

“…However, the theme projected by Chase et al [6] considered the essential threshold-based KP-ABE, that lacks generality within the encoding policy expression. several attribute based encoding schemes having multiple authorities have been projected later [7]- [10], however they either additionally use a threshold-based ABE [7], or have a semi-honest central authority [8]- [10] haphazardly several users' collusion attack [7]. The work by Lewko et al [11] and Muller et al [12] square measure the most similar ones to in this they additionally tried to alter the central authority within the CP-ABE into multiple ones.…”

Cloud computing could be a revolutionary computing paradigm, that allows versatile, on-demand, and inexpensive usage of computing resources, however the info is outsourced to some cloud servers, and varied privacy considerations emerge from it. Various schemes Supported the attribute-based coding have been projected to secure the cloud storage. However, most work focuses on the info contents privacy and therefore the access management, while less attention is paid to the privilege management and therefore the identity privacy. During this paper, a semi anonymous privilege management theme AnonyControl is proposed to handle not solely the data privacy, however conjointly the user identity privacy in existing access control schemes. Anony Control decentralizes the central authority to limit the identity run and therefore achieves semi anonymity. Besides, it conjointly generalizes the file access management to the privilege control, by that privileges of all operations on the cloud knowledge can be managed in an exceedingly fine-grained manner. Afterwards, the Anony Control-F is presented, that totally prevents the identity leakage and succeed the complete namelessness. The security analysis shows that each Anony Control and Anony Control-F square measure secure under the decisional linear Diffie-Hellman assumption, and new performance analysis exhibits the practicableness of new schemes.

Abstract:The idea is to propose a new decentralized access control scheme for achieving security in data stored in clouds that supports anonymous authentication. In the proposed scheme, the cloud verifies the authenticity of the series without knowing the user's identity before storing data in cloud. Here we also have added feature of access control so that only valid users are able to decrypt the data i.e. stored in cloud. The proposed scheme also prevents replay attacks and supports alteration of data and reading data stored in the cloud. We also address user revocation. Moreover, the proposed authentication and access control scheme is decentralized and robust, unlike the existing access control schemes that are centralized. So that here communication, computation, and storage overheads are comparable to centralized approaches.
