At present cloud computing is going to be very famous technology in IT enterprises. For a company, the data stored is huge and it is very precious. In this era, even sensitive data is stored and shared on the internet using trusted third parties and service providers. The authors propose Hierarchical Attribute-Set-Based Encryption (HASBE) by extending cipher text-policy Attribute-Set-Based Encryption (ASBE) with a hierarchical structure of users. It is implemented using cipher text policy by encrypting and decrypting the data in the cloud so that the cloud system becomes more scalable and flexible by enforcing data owners to share their data with data consumers controlled by the domain authority.
