云存储中一个高效的数据完整性审计方案

A light-weight data auditing scheme for the cloud storage environment

云计算被视为新一代企业IT架构,在诸多领域有着广泛的应用。云计算技术使得应用软件与数据库部署于集中式大型数据中心,在大数据计算、存储方面具有开销低廉、访问便捷等特点。然而,云计算在应用过程中仍存在一系列安全挑战。针对存储在云中的外包数据,本文提出了一个高效的外包数据审计方案,该方案支持云存储中数据完整性验,且具有轻量级计算开销。同时,本文给出了该方案的正确性分析与性能评估。实验结果表明本文所提出的数据完整性审计方案更加高效,且能够满足云存储环境下的数据完整性审计要求。

Cloud computing is considered as a new IT framework for enterprises and has been widely used in various fields. In the cloud environment, application software and databases are deployed in the centralized large data centers which has advantages of low cost, convenient access and so on in terms of big data computation and storage. However, cloud computing has several security challenges. In this paper, we proposed a efficient data auditing scheme for cloud-based storage. This scheme provides cloud-based data integrity verification with light-weight computation cost. Furthermore, we show the correctness and performance analysis of the proposed cloud-based data auditing scheme. The experimental results demonstrate that the proposed scheme in this paper is more efficient and enables to satisfy the requirement of data integrity verification for the cloud storage environment.
