Abstract

A scalable data sharing is a crucial functionality in cloud storage. In this paper we deploy efficient and flexible, privacy share data communication in cloud storage. By the privacy consideration we deploy a public-key cryptosystems that produce constant-size cipher texts such that efficient delegation of decryption rights for all sets of cipher-texts is possible. The granularity is that one can combined all set of secret keys and make it as single key, but encompassing the power of all keys being aggregated that is the secret key holder can release a context-size aggregate key for flexible choice of cipher-text set in cloud storage and remaining encrypted files are confidential. This compact aggregate key can be sent to others as a convenient manner or it stored a limited size of secure data in smart card. We describe a casual security analysis of our schemas in standard model with an application of schemas along with public-key patient controlled encryption (PCE) for flexible hierarchy it has to be.
