Abstract

The explosive growth of multimedia data promotes us to enter the era of big data. To improve the storage efficiency and reduce the management expenditure of these massive data, deduplication is a promising technology to meet these requirements. However, it arises serious privacy concerns and poses new security challenges, such as privacy leakage and unauthorized access. To tackle these problems, in this paper, we propose a novel role symmetric encryption (RSE) algorithm and construct an authorized deduplication scheme (RSEDup) based on the role symmetric encryption to achieve the authorized deduplication in cloud. The RSEDup scheme is the first solution to prevent privacy leakage and achieve the authorized deduplication effectively. Performance evaluation shows the efficiency of the proposed scheme.
