摘要:
 随着云存储的普及和发展,云端数据的安全问题越来越受到人们的关注.针对当存储在云端服务器中的数据文件遭到非法修改或意外损坏时,云存储用户与云端均无法提供使双方信服的凭据进行责任划分的问题,提出了一种基于可信第三方的数据安全可问责方案.该方案以可信第三方为审计的核心与桥梁,在用户与云端任何一方对数据状态持有异议时进行责任追溯.可信第三方针对每次用户数据操作都通过在线状态判断并经相应文件权限认证,只有通过可信第三方在线状态与文件权限审核的用户数据操作才能被系统所认可,并将操作记录保存在双方都无法抵赖的凭据中.实现了利用可信第三方代替用户执行数据审计与问责,可靠并高效地解决了用户对数据状态持有异议但无法追溯的问题.
Abstract:
 With the popularity and development of cloud storage,the security of the data in the cloud has been paid more and more atten-tion . In view of the problem that the user and the cloud service provider cannot offer convincing credentials to duty partition when the data stored in the cloud has been unlawful modification or accidental damage,a data security accountability scheme based on trusted third party is put forward. It,which takes the trusted third party as the core and bond,traces the responsibility when any party has objection. For every user data operations,trusted third party is through the online status judgment and authenticated by the corresponding file permissions. The user data operations only by the trusted third party online status and user data file permissions audit can be accepted by the system and their records are stored in the credentials which the both couldn’ t deny. It uses the trusted third party instead of users to audit and ac-count,and solves the problem reliably and efficiently that the user disagree the data state but cannot trace back.
