摘要
针对现有弹药组网密钥管理方法存在安全连通性与抗俘获能力无法同时兼顾的问题,提出了基于位置时间组合的弹药组网密钥管理方法。该方法所有簇头节点仅装定一个初始密钥,部署后利用节点的位置及时间信息完成广播组网及以后的同步密钥更新及通信密钥生成。仿真验证表明该方法可以自主地利用部署成功节点的位置及时间信息,使静态部署弹药组网簇头节点具有良好的安全连通性的同时具备很强的抗俘获能力。
In view of the existing key management method had a problem that it could not simultaneously get both safe connectivity and anti capture ability,a cluster header node key management method of ammunition net-work based on combination of location and time was proposed in this paper.In this method,all cluster header nodes were setting with the same initial key.The location and time information was used to complete network, the sync key and generate the communication key were updated after the network.The simulation results dem-onstrated that the method could use the location and time of cluster header nod independently which were suc-cessful deployed to make the static ammunition network gateway node of excellent anti capture ability and safe connectivity without base station.
