中文摘要： 近年来，随着云存储大规模应用，云存储数据完整性审计问题引起了广泛的重视，研究者亦提出了具有不同特性的云存储完整性审计协议。然而，当前协议研究与云存储实践存在一定距离：已提出的协议效率较低、支持的功能不完善。为进一步深入解决云存储数据完整性审计问题，本课题致力于研究概念简洁、支持第三方公开审计、支持高效数据更新、可并行运行、支持多存储架构且可证明安全的云存储完整性审计协议。具体研究内容包括：1) 探索一种新颖的云存储完整性审计问题研究思路，即将云存储完整性审计问题建模为分布式字符串匹配问题；2) 基于两种经典分布式字符串匹配算法，研究两类功能完善且高效的云存储完整性审计协议；3) 研究MapReduce模型下并行化本课题提出的协议；4) 研究多存储架构模型下基于分布式字符串匹配的云存储完整性审计协议。本课题的研究成果将进一步加深学术界对此领域的理解、促进工业界对于该问题的进一步解决。

英文摘要： With the recent large-scale adoption of cloud storage, cloud storage auditing has drawn considerable attention from both the industry and the research community. Researchers are also proposing various cloud storage auditing protocols with different functionalities. However, a large gap still exists between the current research and the current industrial cloud storage practice, due to the efficiency and functionality issues of proposed protocols. To resolve the gap, this project aims to study more efficient and practical cloud storage auditing protocols which leverage only simple concepts, support third-party public auditing and efficient data dynamics, enjoy parallel execution, and accommodate diverse real-world cloud storage models. Specifically, this project 1) studies to model the problem of cloud storage auditing as a distributed string equality checking problem; 2) constructs two cloud storage auditing protocols from two classical distributed string equality checking algorithms; 3) parallelizes the proposed protocols in this project which are based on distributed string equality checking by leveraging the MapReduce model; and 4) generalizes the proposed protocols to support diverse cloud storage models. The research results from this project can not only deepen the research community’s understanding on cloud storage auditing, but also enable the real-world industry to further resolve cloud storage auditing.
