摘要

针对云环境下多租户数据的安全隔离的问题，提出了一种基于 L-DHT 的多租户虚拟域隔离构建方法。首先，通过设计一种基于标签 Hash 映射的多租户隔离映射算法，构建了租户资源的均衡映射机制，实现对租户资源的分布式管理；然后，针对映射到同一存储节点上租户数据间的安全隔离与访问，基于谓词加密机制，通过安全标签和租户数据的有效绑定，给出了一种基于标签谓词加密的租户数据隔离存储算法；最后，通过设计多维度的租户数据隔离控制规则，利用对安全标签的解析与认证，层次化地构建起租户间相互独立、逻辑、安全的虚拟域。安全性分析表明，所提方法构建了相互间安全无干扰的租户虚拟域。仿真实验结果表明，映射算法能够更好地实现负载的动态平衡，并通过数据检索效率与访问安全性的对比分析，验证了租户访问数据的安全性与高效性。

Abstract

Aiming at the problem of security isolation of multi-tenant data in cloud environment

a tenant virtual domain isolation construction method based on L-DHT was proposed.Firstly

through the design of multi-tenant isolation mapping algorithm based on label-hash mapping

the balanced mapping mechanism of tenant resources was constructed to realize the distributed management of tenant resources.Secondly

for the security isolation and access between tenant data mapped to the same storage node

based on the predicate encryption mechanism

through the effective binding of security labels and tenant data

a tenant data isolation storage algorithm based on label predicate encryption was designed.Finally

by the design of multi-dimensional tenant data isolation control rules and using the analysis and authentication of security labels

independent

logical and secure virtual domains between tenants were built hierarchically.The security analysis shows that the method constructs tenant virtual domains which are secure and non-interference with each other.The simulation results show that the mapping algorithm can achieve a better dynamic load balance.The efficiency and security of data access are verified by the comparative analysis of tenant data retrieval efficiency and authentication access security.
