基于完整性指示码的数据分散存储和恢复方式
首发时间:2011-04-28
摘要:电子数据由于其自身特点,在存储过程中极易被篡改、伪造、破坏或毁灭。人们提出了称为完整性指示码的细粒度数据完整性检验方法。该方法在实现完整性检验的同时可以对少数错误进行准确和高效的隔离,但现有方法没有考虑到完整性数据的安全。本文提出了改进的数据分散存储与恢复方法,增强了完整性数据的容错能力,从而改善数据存储的安全性。根据超方体完整性指示码和复数旋转完整性指示码等编码的不同特性,具体设计了三种实现方式。这三种方式都能在一定程度上提高了完整性数据的容错能力,增加完整性数据的可信度和可用性,进而增加了原始数据的可信度和可用性。

Data Distributed Storage and Recovery Way Based on Integrity Indication Code
Abstract:Electronic data can be tampered, forged, damaged or destroyed easily on store procedure because of its own characteristics. So people proposed the fine-grained data integrity checking methods which named integrity indicator code. This method can achieve integrity checking and can also isolate a few mistakes accurately and efficiently. But this method assumes that the data which is used for integrity checking. This paper proposed an improved distributed data storage and recovery method to enhance the ability of fault tolerance of integrity data and improve the security of data storage. Base on the characteristics of hyper cubes integrity indicator code and plural rotating integrity indicator code. These three ways can improve the fault tolerance of hash data,and increase the credibility and availability of the integrity data,and then increase the credibility and availability of the primitive data.
