Abstract: Cloud computing is a most convenient and popular way for data sharing which brings various benefits like providing computational resources on demand, cost saving, agility, scalability and flexibility for societyas well as for individuals. The massive amount data shared on cloud storage system contains very valuable information which should provide a high security to data. Cipher text policy attribute based encryption (CP-ABE) is most used technology to deal with the challenge of providing secured data. In existing CP-ABE schemes, data owner has full authority to control the access policy of shared data on cloud. However CP-ABE leads to key escrow problem and also fails to support many facilities to the users of the data. In this paper we are revisiting the attribute based data sharing scheme in order to remove the key escrow problem as well as improve the efficiency and security of shared data resources on cloud storage

Keywords: Cloud Computing, Attribute Based Encryption, Secure Data Sharing, Removing Key Escrow, And Key Distribution
