一种支持动态更新的远程数据完整性验证方法

摘要

论文针对云存储中数据外包的特性，提出了一种支持数据动态更新的远程数据完整性验证方案，利用数据更新信息表支持数据的修改、插入、删除等动态操作，在椭圆曲线上的双线性配对算法的基础上设计了一个远程数据完整性验证方案，并对方案的正确性和性能进行了分析，分析表明该文方案是可行的。%On the basis of the issue of outsourced data ,a remote data integrith verification scheme which supports data dynamics updating is proposed .A data updating information table is designed to support data transact ,insert and delete .A remote data integrity verification scheme based on bilinear pairing algorithm of elliptic curve is proposed .The analysis of the correctrness of the scheme and performance shows that this scheme is feasible .
