A novel secure cloud storage architecture combining proof of retrievability and revocation
Deepnarayan Tiwari, G. R. Gangadharan · 2015
The outsourcing of data into the cloud inherently requires a mechanism to control the access capability of the users and the cloud providers. This mechanism requires efficient cryptographic primitives to achieve fine grained access control of data, proof of storage, and revocation of the authorization. In this paper, we present a secure cloud data storage architecture with the features of dynamic user construction, revocation of the authorization, and proof of storage. In the proposed architecture, we used attribute based broadcast encryption, attribute based access control, and proxy re-encryption to achieve an efficient solution.
