【摘要】:為了在分布式環(huán)境下進行數(shù)據(jù)持有性驗證并保持較低的修復帶寬,該文在引入再生碼的基礎上,提出了一種分布式環(huán)境下的數(shù)據(jù)持有性驗證方案。該方案利用再生碼來進行數(shù)據(jù)持有性驗證,并在修復階段再次進行持有性驗證以抵抗污染攻擊。通過理論分析,該方案既保持了再生碼修復帶寬低的優(yōu)勢,且相比于經典方案降低了計算開銷,節(jié)省了存儲空間。該文還提供了方案的安全性證明,通過安全性及性能分析表明該方案是可行的。
[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.
