一种改进的云存储数据完整性验证方法

摘要

Most existing cloud storage data integrity verification methods have low efficiency and high communication overhead.To solve this problem, an improved data integrity verification method for cloud storage is proposed.The bilinear pairing technique is used to verify the data integrity in order to realize the public verification function.The indexing table mechanism is designed for dynamic verification.The random mask technique is used to improve the security of the method.Analysis and experimental results show that this method can effectively resist malicious attacks on servers, and has lower communication overhead and higher computing efficiency.%已有多数云存储数据完整性验证方法效率较低、通信开销较大.为此, 提出一种改进的云存储数据完整性验证方法.利用双线性对技术进行数据完整性验证以实现公开验证功能, 设计索引表机制进行动态验证, 采用随机掩码技术提高方法的安全性.分析与实验结果表明, 该方法能有效抵抗服务器的恶意攻击, 且具有较低的通信开销与较高的计算效率.
