摘要:

针对当前基于 RC 编码的容错技术的安全缺陷,提出了一种安全编码——SRCS 编码,以保证在云计算以及云存储这种高度开放环境下,存储系统容错过程中数据的安全性。该编码将门限体制引入到了传统的RC编码当中,利用基于公钥的门限体制保护编码矩阵,在确保基于传统RC编码的容错技术高效、低冗余优势的前提下,解决了其在开放环境下编码矩阵存在的安全问题。最后利用判定性BDHE假设,在部分适应性攻击模型下证明了SRCS编码的安全性。

Abstract:

A secure regenerating code,called SRCS was proposed to solve the security problem during the process of the fault-tolerant of storage systems,especially the storage system in an extremely open environment such as cloud computing and cloud storage.SRCS achieves the security of the encoding matrix in the regenerating code using the threshold public-key encryption with low redundancy and high efficiency.It is proven that SRCS is secure in the semi-adaptive model using decisional BDHE assumption.

Key words: regenerating codes, fault-tolerant, cloud computing, cloud storage, threshold public-key encryption, decisional BDHE assumption
