| 摘 要： | 用户数据安全和隐私保护是云计算面临的巨大挑战。公开验证方案中的数据通信、数据存储、完整性与可用性验证、动态数据、数据签名等不同操作对数据粒度的需求不同。本文将数据文件组织为块、子块和基本块三种不同的粒度,提出一种支持不同粒度运算的完整性验证方案。该方案支持公开审计和数据块动态操作。分析了方案的安全性、通信性能、存储性能,结果表明新方案是高效的、安全的。

| Abstract: | Data security and privacy protection are big challenges of the cloud computing.Different operations in public auditing scheme,such as data communication,data storage,integrity and availability checking,dynamic data,data signature have different demands on the data granularity.The paper proposes an integrity checking scheme with different granular operation.In the proposed scheme,the data is divided into three different granularities insisting of block,sub-block and basic block.The scheme supports public auditability and data block dynamics.The performances of the communication and storage as well as the security are analyzed.The results show that our scheme is efficient and secure. |
