AbstractSince the advent of cloud its has become a efficient platform for sharing data for big enterprises, companies, startups and individuals. Cloud has allowed multiple users to collaborate on data. A certain level of security is desired by the cloud users while sharing data. Data owners would want to store their data on the cloud while preserving confidentiality and would want to allow access or provide decryption details to the users he wants to share data with along with the ability to revoke that access ant any given time. In this paper the system proposed uses broadcast encryption to encrypt the data while using the cloud resources efficiently by reducing the overhead caused in the Key Aggregate Cryptosystem (KAC).
