摘要:随着网络技术的迅速发展,基于云计算的应用已经渗透到社会的各个领域。云存储数据完整性技术是云计算的重要内容。然而,目前还缺乏对云存储数据完整性进行有效验证和分析的方法。提出了一种云存储数据完整性验证方法,该方法结合可恢复性证明(PoR)和MD5的优势,利用数据分块、随机抽样和周期性验证技术及时验证出数据是否被损坏。具体实现及分析结果表明,该方法能有效地验证云存储数据的完整性,有助于提高云计算的安全性。
Cloud computing has been widely applied in many fields with the development of internet technology, in which data integrity techniques play an important role. However, there are few effective approaches to analyze and verify the data integrity. In this paper, by combining the advantage of PoR (Proof of Retrievability) and MD5(Message Digest), a new approach to verifying the integrity of the cloud stored data is proposed, in which the technologies, such as data block, random sampling and periodic verification are used. It is shown from real implementation and analysis results that the proposed method can effectively verify the data integrity of cloud stored data and improve the security of cloud computing.
