SECURE AND ENERGY EFFICIENT DATA SHARING IN PUBLIC CLOUD THROUGH MOBILE DEVICES

Abstract

The people wants to reduce the search time
and retrieve the relevant information by using the
cloud database instead of search the data in all over
the internet. In this most of the service providers
make their database as public that will be used by
any people who wants to store and share the data in
closed group and they want to access in mobile
environment. But, while sharing data among multiple
users of multiple owners requires identity privacy to
obtain the specific owner’s data. In this paper, a
secure data sharing scheme for individual users for
specific data owner is proposed to retrieve the data
in the public cloud through mobile devices. By
creating individual signature for individual user with
respect to each group and broadcasting encryption
techniques dynamically. This proposed system uses
Individual User attribute based encryption (IU-ABE)
for encryption and decryption of storage information
and access by any mobile devices in an energy
efficient manner. Meanwhile, the storage overhead
and encryption computation cost of proposed system
are independent based on the number of users access
the data
