With the proliferation of new mobile devices, mobile cloud computing technology has emerged to provide rich computing and\nstorage functions for mobile users. The explosive growth of mobile data has led to an increased demand for solutions that conserve\nstorage resources. Data deduplication is a promising technique that eliminates data redundancy for storage. For mobile cloud\nstorage services, enabling the deduplication of encrypted data is of vital importance to reduce costs and preserve data confidentiality.\nHowever, recently proposed solutions for encrypted deduplication lack the desired level of security and efficiency. In\nthis paper, we propose a novel scheme for serverless efficient encrypted deduplication (SEED) in mobile cloud computing\nenvironments. Without the aid of additional servers, SEED ensures confidentiality, data integrity, and collusion resistance for\noutsourced data. The absence of dedicated servers increases the effectiveness of SEED for mobile cloud storage services, in which\nuser mobility is essential. In addition, noninteractive file encryption with the support of lazy encryption greatly reduces latency in\nthe file-upload process. The proposed indexing structure (D-tree) supports the deduplication algorithm and thus makes SEED\nmuch more efficient and scalable. Security and performance analyses prove the efficiency and effectiveness of SEED for mobile\ncloud storage services.
