Dynamic group key authentication mechanism for data sharing in network

Abstract

In the network data sharing is an important functionality. In many organizations data owners store their data into the storage server which can certainly share data with other followers (users). Earlier approaches either unreasonably expose the uniqueness of a data owner to the untrusted server or any unexclusive vouchers, or innovate substantial expenses on confirmation metadata to preserve concealment. In the proposed system, group manager is introduced and takes charge of user registration, and enlightening the real uniqueness of a dispute data proprietor. Group manager will generate a key and provide to the user, who want to access the data from the storage server. Consequently proposed method reduces the computation overhead and provides high performance due to revoke verification procedure.
