基于外包存储的数据完整性检验的研究

Research on Integrity Checking of Data Based on Outsourced Storage

近年来,外包存储获得了越来越广泛的应用,与此同时其安全性问题也备受人们的关注。特别是它需要一个有效的机制确保用户存储在远方不可信服务器上的数据没有被篡改,这也就是数据的完整性检验。完整性检验是不可信外包存储服务的至关重要的方面。讲述了两种有效的数据完整性验证的机制,并进行了比较分析,最后归纳总结了各自的优缺点及适用情况。

Outsourced storage has become more useful in application in recent years,at the same time its security issues also have been concerned by many people. An important issue for outsoureed storage systems is to design an efficient scheme to assure users that their data stored at remote servers has not been tampered with, namely integrity Checking of data . Integrity checking of data has emerged as a critical problem in storing data on unreliable servers. This paper presents two efficient scheme for integrity checking of data, and by comparing and analyzing them, summarizes their advantages and disadvantages as well as the situation they adapt to.
