摘要: 云计算在给用户带来便利的同时,也为用户数据带来了新的安全挑战。其中数据完整性成为用户担心的安全问题之一。由于现有云存储环境下数据完整性验证方案只适合对单个数据文件进行完整性验证,因此提出一种新的改进方案。改进后的方案不仅支持多备份数据的完整性验证,而且支持备份数据在验证过程中的隐私保护。通过对改进方案的安全性、可行性进行详细的分析,说明改进后方案是安全和高效的。

Abstract: Cloud computing, with bringing convenience to consumer, also poses new security challenges to consumer data. Where the data integrity is one of the security issues that consumer worry about. We first analyse the deficiency of existing data integrity verification scheme in cloud storage environment, in which we can only validate the individual data file, then present a new improved scheme. The latter not only supports the integrity verification of multiplcreplication data,but also supports the data privacy protection in the process of validation. I3y security and feasibility analysis of improved scheme in more details,we indicate that the improved scheme is secure and effective.

Key words: Cloud storage, Data integrity, Privacy protecting, Multi-copy
