摘　　要：重载群组列车自组织网络依赖先进的无线通信技术实现列车之间以及列车与基础设施之间的数据交换。为保护传输的数据不被未授权访问和篡改,基于此,提出一种适用于重载列车自组织网络环境下的安全通信方案。首先,建立重载群组列车的信息模型,信息层利用图论表示列车的通信拓扑结构。其次,为应对重载群组列车自组织网络的动态变化,设计一种基于轻量环签名的去中心化匿名身份验证和授权机制,以抵御群组列车外部的通信攻击。最后,仿真验证所提方案的安全性和轻量性,结果表明所提方案能在抵御外部通信攻击的同时,降低22.7%的计算开销。The ad hoc network of heavy-haul group trains relies on advanced wireless communication technology to exchange data between trains and between trains and infrastructure.In order to protect the transmitted data from unauthorized access and tampering,based on this,a secure communication scheme suitable for heavy-haul trains is proposed.Firstly,an information model of heavy-haul group trains is established,and the information layer uses graph theory to express the communication topology of trains.Secondly,in order to cope with the dynamic changes in the ad hoc network of heavy-haul group trains,a decentralized anonymous authentication and authorization mechanism based on lightweight ring signatures is designed to resist communication attacks outside the group trains.Lastly,simulations verify the security and lightweight nature of the proposed scheme.The results show that the proposed scheme can resist external communication attacks and reduce computing overhead by 22.7%.
