摘要
作为云计算的重要分支,云存储以高性能和低成本等优势吸引了越来越多的组织和个人将大规模数据托管于其上。然而,云数据的外包特性和近年来频繁爆出的安全事件,使得用户对云存储服务的信心不足,其关键问题是如何确保存储在云端的数据的完整性。为应对该挑战,云数据持有性审计在最近几年被提出并受到了广泛的关注,文中对此进行了综述。首先,回顾了云数据持有性审计的一般模型和审计系统的设计目标;其次,按照实现的审计功能,对近年来的研究成果进行了分类介绍及对比分析;最后,指出了云数据持有性审计研究中存在的开放问题及发展趋势。
As an important branch of cloud computing,cloud storage possesses the advantages of low-cost and high-performance,and has attracted a growing number of organizations and individuals to outsource their data.However,due to the outsourcing characteristic of cloud data and frequent security accidents for cloud storage providers,users are lacking of confidence in the cloud storage server,of which the main problem is how to effectively check the integrity of cloud data.To overcome this challenge,the auditing for cloud data possession has been proposed and gotten widespread attention in recent years,and a comprehensive survey was provided in this paper.First,general models and design goals of the auditing for cloud data possession were reviewed.Second,the existing auditing schemes for cloud data possession were classified according to their auditing functions,their principles were analyzed,and their performances were compared.Finally,the open problems in the auditing for cloud data possession were identified,and the trends of future development were discussed.
