摘要
数据外包云存储是当前主流的海量数据存储方式,这种模式下用户失去对其数据的绝对控制权,恶意租户或云服务内部人员可能会篡改或破坏云端数据,如何确保非可信云存储环境下外包数据的完整性是制约云计算发展的重要安全问题。文章对现有的数据完整性审计工作进行综述,基于对外包数据完整性审计问题的统一抽象给出审计模型分类,结合支撑数据动态操作、计算和通信开销等审计目标,从审计中用户关键数据是否共享的视角分类,对当前典型方案进行了对比分析和优缺点讨论,最后总结了外包数据完整性审计的未来发展方向。
Data outsourcing cloud storage is the current mainstream mass data storage method.However,in this mode,data owners lose absolute control over data,and cloud data may be tampered with or destroyed by malicious tenants or internal personnel of cloud service providers.How to ensure the integrity of outsourced data stored on untrusted clouds is an important problem that restricts the development of cloud storage.This paper summarizes the existing data integrity audit work,gives the classification of audit models based on the unified abstraction of outsourcing data integrity audit issues,and compares and analyzes the current typical schemes and discusses their advantages and disadvantages from the perspective of whether users’ key data are shared in the audit in combination with the audit objectives such as supporting data dynamic operation,calculation and communication overhead.Finally,it summarizes the future development direction on integrity auditing of outsourcing data.
