一种可扩展的动态数据持有性证明方案

摘要

This paper proposed a dynamic provable data possession scheme that could protect data privacy.And it proved that the scheme was secure.It was also showed that its payload on storage,computation and transfer was low.Then,it extended the scheme to support public verifiability and multiple replicas checking.The characteristic of the publicly verifiable scheme need not trusted third party,and the multiple replicas checking one can support batch checking very well.%提出了一种能保护数据隐私的动态数据持有性证明方案,并对方案的安全性进行了证明,性能分析表明该方案具有低存储、计算和传输负载的特点.通过扩展实现了对公开可验证和多副本检查的支持,扩展方案的特点在于公开验证中不需要可信第三方的参与,而多副本检查可以方便地实现对所有副本的批量检查.
