Cloud Computing is a promising and emerging technology that is rapidly being adopted by many IT companies due to a number of benefits that it provides, such as large storage space, low investment cost, virtualization, resource sharing, etc. Users are able to store a vast amount of data and information in the cloud and access it from anywhere, anytime on a pay-per-use basis. Many users are able to share the data and the resources stored in the cloud. Hence, there arises a need to provide access to the data to only those users who are authorized to access it. This can be done by enforcing access control schemes which allow only the authenticated and authorized users to access the data and deny access to unauthorized users. In this paper, a comprehensive review of all the existing access control schemes has been discussed along with the analysis of these schemes.Index Terms: Role-based access control, attribute-based access control, attribute-based encryption.

Abstract-Ciphertext-Policy Attribute-Based Encryption (CP-ABE) is a promising cryptographic mechanism for fine-grained access control to shared data. Attribute/Key management is a keystone issue in CP-APE because of low efficiency of existing attribute revocation techniques. Indeed, existing solutions induce great side effect after each attribute revocation. The side effect induces rekeying and/or re-assignment of attributes to all users.In this paper, we propose a solution which does not require extra entities like proxies to re-encrypt data after every access policy change. Moreover, our solution does not imply latencies following access grants and revocations. We compare our solution with the batch-based CP-ABE attribute management technique and we show that our solution outperforms existing rekeying/revocation techniques in terms of overhead.
