The authors propose a perfect key aggregate system with scalable sharing of data in cloud. This scheme provides secure data storage and retrieval. Along with the security the access policy is also hidden for hiding the user's identity. This scheme is so powerful since they use AES and improved Diffe-Hellman key exchange technique in a single scheme. The novelty is that one can aggregate any set of secret keys and make them as compact as a single key, but concluding the power of all the keys being aggregated. The scheme detects any change made to the original file and if found clear the error's.
