ABSTRACT

In order to improve the efficiency and security of multi-copy dynamic cloud data audit, a multi-copy dynamic cloud data auditing model (MCAM) based on IMB tree is proposed. The IMB tree makes the audit process fast and efficient while maintaining security. Multi-copy compression transmission with masking rate is introduced to better reduce migration time. The theoretical analysis shows that MCAM can resist forgery attacks in the audit process and avoid information leakage. In addition, compared to the Merkle tree auditing solution, MCAM has improved data migration efficiency by about 17% and saved 24% of time consumption.

基于IMB树的多副本动态云数据审计模型

摘要

为了提高多副本动态云数据审计的效率和安全性，提出了一种基于IMB树的多副本动态云数据审计模型（MCAM）。IMB树使审核过程既快速又有效，同时又保持了安全性。引入具有屏蔽率的多副本压缩传输以更好地减少迁移时间。理论分析表明，MCAM可以抵御审计过程中的伪造攻击，避免信息泄露。此外，与Merkle树审核解决方案相比，MCAM将数据迁移效率提高了约17％，并节省了24％的时间消耗。
