摘　　要：基于B+树特性和双线性对技术,提出了1种新的多副本数据完整性验证方案。通过引入经典B+树认证结构并设计轻量级系统模型,使用户能及时掌握云服务器端多副本数据的完整性和一致性情况;在B+树中加入rank值,使用户能快速准确定位错误数据的位置,便于下一步处理。实验结果证明,所提方案能降低系统模型中各实体的计算开销和通信开销,提高验证效率。Based on B＋tree and bilinear pairing technique,a novel multiple-replica data integrity verification scheme was presented in this paper.We introduce the classic B＋tree authentication structure and design a lightweight system model,so that users can keep abreast of the integrity and consistency of multiple-replica data on the cloud server side.Moreover,we add rank values in the B＋tree so that users can accurately pinpoint the location of the wrong data.Experimental results show that the scheme effectively reduces the computational and communication costs of each entity and improves the efficiency of verification.
