摘要

利用认证数据结构(ADS

authenticated data structures)的安全特性

分析并设计了面向云计算的基于ADS的数据外包认证模型

给出了模型的形式化定义、数据查询认证协议与数据更新认证协议;对ADS在模型实际应用时遇到的关键问题进行分析

设计了扩展数据一致性证据生成算法和扩展验证算法

从而实现了ADS在模型中的有效融入。最后从安全性和效率两方面对模型的性能进行分析比较

结果表明模型以较高效率实现了数据的正确性与一致性认证。

Abstract

The outsourcing authentication model based on authenticated data structures was proposed.The formal defini-tion

data query authentication protocol and data updating authentication protocol of the model was presented.The crucial problems when the authenticated data structures are being used were analyzed.With designing the new extended coher-ence proof generation algorithm and the new extended verifying algorithm

authenticated data structures in the model very well was used.Finally the model with others through the performance analysis including the security and efficiency

the results of which show that:the model is more efficient than others as well as the consistency and correctness require-ments are also guaranteed.
