云环境下基于BN模型的虚拟机安全部署模型

摘要

CVDBN security deployment model of virtual machine was proposed in allusion to security risk caused by multiple consumers' sharing hardware resource in the environment of cloud computing and the security rules of subject server to deploy the object virtual machines were designed based on BN model, which can meet users' isolation requirement on deployment of virtual machines with interest conflict. In the end, the security module of deploying virtual machines and the security algorithm of deploying virtual machines were designed. Simulation was conducted which demonstrates the effectiveness and availability of the model and algorithm proposed in this context.%针对云计算环境下多用户共享硬件资源带来的安全风险,提出了虚拟机安全部署模型CVDBN,基于BN模型设计了安全部署规则,以满足云计算环境下利益冲突用户对于虚拟机部署的安全隔离需求.最后设计了虚拟机安全部署模块和安全部署算法.仿真实验结果证明了该模型和算法的有效性和可用性.
