摘要:

为了降低面向再生编码分布式存储系统的外包数据审计机制的安全实现开销,提出了一种正交化代数编码方法,以此构造一类基于线性同态认证的轻量型隐私保护审计方案。利用文件编码数据与私有密钥向量的正交化构造外包存储向量的同态认证标签,并提出利用密钥特定分量的正交基向量组的随机化掩码来完成审计响应消息的隐私保护,实现代数编码、隐私保护和安全审计的高效融合。理论分析表明,所提方案在再生编码分布式存储应用中可实现信息理论意义下的安全性。与现有同类工作相比,该方案计算复杂度低,通信开销小,具有更好的性能优势。

Abstract:

To reduce the security implementation cost of the outsourcing data audit mechanism for the regenerating-coding-based distributed storage systems, an orthogonal algebraic coding method was put forward to construct a lightweight privacy-preserving audit scheme based on linear homomorphic authentication.The homomorphic authentication tags were generated with the orthogonalization between the file encoded data and the private secret key vector, and the privacy protection of the auditing response message was achieved by using the random masking that was constructed by randomizing the orthogonal basis vectors of the specific sub-vector of the user’s secret key.The work realized the effective integration of algebraic coding, privacy protection, and security auditing.Theoretical analysis shows that the proposed scheme can realize the information-theoretic security in the regenerating-coding-based storage applications.Compared with the existing works, the proposed scheme is of low computational complexity and communication overhead, and better performance advantages.

Key words: data auditing, privacy protection, regenerating code, network coding, distributed storage
