Access Control and Revocation for Digital Assets on Cloud with Consideration for Sharing

摘要

In cloud computing applications, users' data and applications are hosted by cloud providers. With internet and cloud availability increasing numbers of people are storing their content on cloud. Also with presence of social networking, contents stored on cloud are also shared. This requires more security for the contents on cloud. Traditional security solution address only encryption, decryption of data on cloud and its access control , but with this new trend of sharing, the scope of security becomes even higher. In this paper we propose a solution of integrated access control for contents shared on cloud and its efficient revocation.
