Adoption of cloud services that have biggest obstacles is that security challenges when considering it. Current approach is that hosting the confidential data in cloud based on fine-grained encryption of data by fine grained access control. In this approach, before uploading the data, data owners should encrypt the data and whenever the user changes. Data owners incur high communication and computation costs. To achieve security and confidentiality, we make use of approach base don’t layers of encryption, that addresses such requirement. Under this approach, the data owner performs a coarse-grained encryption, where in cloud performs a fine-grained encryption on to the owner encrypted data. We utilize an efficient group key management scheme that supports ACPs. Our system as sure the confidentiality of the data and preserves the privacy of users from the cloud while delegating most of the access control enforcement to the cloud.
Conclusion
Current approaches to enforce ACPs on outsourced data using selective encryption require to manage all keys and encrypts data to upload to the remote storage. This approach has high communication and computation cost to manage keys and encryptions whenever user change. A key problem is how to decompose ACPs so that the Owner has to handle a minimum number of attribute conditions. Our approach is based on a privacy preserving attribute based key management scheme that protects the privacy of users while enforcing attribute based ACPs. As the experimental results show, decomposing the ACPs and utilizing the two layers of encryption reduce the overhead at the Owner. As future work is to investigate the alternative choices for the TLE approach and to reduce the computational cost by exploiting partial relationships among ACPs.
