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

在移动云计算环境中实现无服务器高效加密重复数据删除

随着新移动设备的激增,移动云计算技术应运而生,可以为移动用户提供丰富的计算和存储功能。移动数据的爆炸性增长导致对节省存储资源的解决方案的需求增加。重复数据删除是一种有前途的技术,它消除了用于存储的数据冗余。对于移动云存储服务,启用重复数据加密对降低成本和保持数据机密性至关重要。但是,最近提出的用于加密重复数据删除的解决方案缺乏所需的安全性和效率。在本文中,我们提出了一种用于移动云计算环境中的无服务器高效加密重复数据删除(SEED)的新方案。SEED无需额外的服务器,即可确保机密性,数据完整性,以及对外包数据的抗共谋性。缺少专用服务器可提高SEED在移动云存储服务中的有效性,在这些服务中,用户移动性至关重要。此外,在支持惰性加密的情况下,非交互式文件加密大大减少了文件上传过程中的延迟。提出的索引结构(D-tree)支持重复数据删除算法,从而使SEED更加高效和可扩展。安全性和性能分析证明了SEED在移动云存储服务中的效率和有效性。支持惰性加密的非交互式文件加密大大减少了文件上传过程中的延迟。提出的索引结构(D-tree)支持重复数据删除算法,从而使SEED更加高效和可扩展。安全性和性能分析证明了SEED在移动云存储服务中的效率和有效性。支持惰性加密的非交互式文件加密大大减少了文件上传过程中的延迟。提出的索引结构(D-tree)支持重复数据删除算法,从而使SEED更加高效和可扩展。安全性和性能分析证明了SEED在移动云存储服务中的效率和有效性。
