发布时间：2018-10-12 16:05
【摘要】：为了在分布式环境下进行数据持有性验证并保持较低的修复带宽,该文在引入再生码的基础上,提出了一种分布式环境下的数据持有性验证方案。该方案利用再生码来进行数据持有性验证,并在修复阶段再次进行持有性验证以抵抗污染攻击。通过理论分析,该方案既保持了再生码修复带宽低的优势,且相比于经典方案降低了计算开销,节省了存储空间。该文还提供了方案的安全性证明,通过安全性及性能分析表明该方案是可行的。
[Abstract]:In order to verify data holding in distributed environment and maintain low repair bandwidth, this paper proposes a verification scheme for data holding in distributed environment based on the introduction of regenerative codes. The scheme uses regenerative codes to verify the data holding, and performs the possession verification again in the repair stage to resist the pollution attack. Theoretical analysis shows that the proposed scheme not only maintains the advantage of low recovery bandwidth, but also reduces the computational overhead and saves the storage space compared with the classical scheme. The security proof of the scheme is also provided. The analysis of security and performance shows that the scheme is feasible.
