An Efficient Access control scheme for Outsourced Data

In this paper, we analyze Liu et al.’s scheme and show that their scheme is not secure. Then we modify their scheme and present an efficient access scheme to outsourced data. Our scheme adopts two-layer encryption model and all users are divided into different groups according to their access privilege. We employ filter functions to construct the key derivation procedure to prevent the revoked ...
