Abstract
Recently, cloud storage is a gaining popularity. In enterprise settings, rise in demand for data outsourcing, which assists in the strategic management of corporate data. However, users are also increasingly concerned about inadvertent data leaks in the cloud. Such data leaks, caused by a malicious adversary or a misbehaving cloud operator, can usually lead to serious breaches of personal privacy or business secrets. A key challenge to designing such encryption schemes lies in the efficient management of encryption keys. A projected a economically implementable edition KAC among small transparency cipher texts as well as collective key, use pairing. It is able to be economically shared through broadcast encryption provide towards information user as well as information owner whereas falling the reducing the protected waterway constraint. It also allow user to decrypt numerous module of information using the single input of stable range which could economically broadcast towards numerous user. Our planned scheme has proved in secure and practically efficient.
