摘　　要：恶劣的通信环境、终端频繁的移动以及节点的能量限制,给战术物联网环境下节点安全性评估带来了极大挑战。针对这一问题,提出了一种移动战术环境下使用信任指标对节点进行安全性评估的方案。该方案引入通信稳定性作为信任指标的影响因子,解决了机会服务攻击和开关攻击的安全问题。仿真结果表明,该方案能够进行入侵检测,有效地发现恶意节点,较好地抵抗多种已知攻击。此外,该方案在保证安全性的同时能够大大降低能耗,是一种既安全又轻量的方案。The harsh communication environment,frequent movement of terminals,and energy constraints of nodes have brought great challenges to the security assessment of nodes in the tactical IoT environment.In response to this problem,this paper proposes a scheme to evaluate the security of nodes using trust metrics in a mobile tactical environment.This scheme introduces communication stability as an influencing factor of trust metrics,an solves the security problems of opportunistic service attacks and On-off attacks.Simulation results indicate that the scheme can carry out intrusion detection,effectively find malicious nodes,and better resist a variety of known attacks.Moreover,this solution can greatly reduce energy consumption while ensuring safety,and is a safe and lightweight solution.
