摘要:

随着云存储的快速发展,越来越多的用户将数据存储在云端。为了验证云端的用户数据是否损坏,一种有效的方法是采用云存储完整性检测方案。利用理想格上的小整数解问题,设计了一种基于身份的云存储完整性检测方案,并在随机预言模型下证明了所提方案可以抵抗云服务器的适应性选择身份攻击。为了验证方案的效率,通过实验将所提方案与现有的2种基于身份的云存储完整性检测方案分别进行了比较。实验结果显示,所提方案的标签在线生成时间降低了88.32%~93.74%,证据验证时间降低了98.81%~99.73%。

Abstract:

With the rapid development of cloud storage,more and more users are storing their data in the cloud.To verify whether the users’ data stored in the cloud is corrupted,one effective method is to adopt cloud storage integrity checking schemes.An identity-based cloud storage integrity checking scheme was proposed on the small integer solution problem over ideal lattices,and it was proven to be secure against the adaptive identity attacks of clouds in the random oracle model.To validate the efficiency of the scheme,extensive experiments were conducted to make performance-comparisons between the scheme and the existing two identity-based cloud storage integrity checking schemes.The experimental results show that the online tag-generation time and the proof-verification time of the scheme are respectively reduced by 88.32%~93.74% and 98.81%~99.73%.

Key words: lattice, identity-based cryptography, cloud storage, integrity checking
