Cloud storage security has gained considerable research efforts with the wide adoption of cloud computing. As a security mechanism, researchers have been investigating cloud storage auditing schemes that enable a user to verify whether the cloud keeps the user's outsourced data undamaged. However, existing schemes have usability issues in compatibility with existing real world cloud storage applications, error-tolerance, and efficiency. To mitigate this usability gap, this article proposes a new general cloud storage auditing scheme that is more usable. The proposed scheme uses the idea of integrating linear error correcting codes and linear homomorphic authentication schemes together. This integration uses only one additional block to achieve error tolerance and authentication simultaneously. To demonstrate the power of the general construction, we also propose one detailed scheme based on the proposed general construction using the Reed Solomon code and the universal hash based MAC authentication scheme, both of which are implemented over the computation-efficient Galois field $\mathrm {GF}{(2^8)}$ GF (28). We also show that the proposed scheme is secure under the standard definition. Moreover, we implemented and open-sourced the proposed scheme. Experimental results show that the proposed scheme is orders of magnitude more efficient than the state-of-the-art scheme.

迈向可用的云存储审计

随着云计算的广泛采用，云存储安全性得到了大量的研究成果。作为一种安全机制，研究人员一直在研究云存储审计方案，使用户能够验证云是否保持用户的外包数据完好无损。然而，现有方案在与现有现实世界云存储应用程序的兼容性、容错性和效率方面存在可用性问题。为了缩小这种可用性差距，本文提出了一种新的通用云存储审计方案，该方案更有用。所提出的方案使用了将线性纠错码和线性同态认证方案集成在一起的思想。这种集成仅使用一个额外的块来同时实现容错和身份验证。$\mathrm {GF}{(2^8)}$ GF (28). 我们还表明，所提出的方案在标准定义下是安全的。此外，我们实施并开源了所提出的方案。实验结果表明，所提出的方案比最先进的方案效率高几个数量级。
