摘　　要：移动边缘计算中任务多在远离服务中心的边缘节点上执行,边缘节点的安全能力并不能得到保障,如何将任务迁移到安全可靠的边缘节点来执行是当前存在的一个问题。针对移动边缘计算下任务迁移中的安全风险问题,构建了适用于移动边缘计算环境的移动Agent安全风险计算模型,通过风险采集、风险处理和风险反馈综合评估边缘节点的抗风险值;并引入动态免疫算法,在任务计算和安全计算时间满足任务截止时间的前提下,实现任务迁移的安全能力最大化。仿真实验表明,相比于传统的任务迁移方案,该策略大大提高了移动边缘计算中任务迁移的抗风险能力,具有一定的鲁棒性。In mobile edge computing,most tasks are executed on the edge nodes far away from the service center,so the security capability of the edge nodes cannot be guaranteed.How to migrate tasks to secure and reliable edge nodes is a current problem.Aiming at the problem of security risk in task migration under moving edge computing,the paper proposes a mobile Agent security risk computing model suitable for mobile edge computing environment.The anti-risk value of the edge node is evaluated comprehensively through risk collection,risk processing and risk feedback;The dynamic immune algorithm is introduced to maximize the security capability of task migration on the premise that the task computation and security computation time meet the task deadline.Simulation results show that compared with the traditional task migration schemes,this strategy greatly improves the anti-risk ability of task migration in mobile edge computing and has certain robustness.
