摘　　要：针对车联网无线链路中网络节点容易受到攻击和欺骗的问题,提出了一种基于开放式最短路径优先(Open shortest path first,OSPF)的新型安全链路状态路由协议(Secure link state routing protocol,SLSRP)算法。构建了基于动态贝叶斯网络的信任量模型,用于实现节点的身份验证和完整性评价。在标准OSPF的基础上进行了可信化改进,引入了基于组合公钥(Combined public key,CPK)的安全认证技术,实现了新的安全链路状态路由协议。研究结果表明,所提出的算法在网络遭受攻击时,能够及时获取节点可信度的变化,在同等环境中具有更好的动态适应性和时效性,有利于用户选择更安全可信的信息传输路径。In response to the attacks faced by vehicular networks,this study focuses on the issues of network node attacks and deception.A new Secure link state routing protocol(SLSRP)is proposed.This protocol is based on the Open shortest path first(OSPF)protocol and incorporates a trust metric model based on a dynamic Bayesian network,combined with security authentication technology based on Combined public key(CPK),to select safer paths for information transmission.The research on the secure routing protocol includes both node security and the security of node information exchange.By establishing a trust metric model,the protocol completes node identity authentication and integrity evaluation,enhancing the standard OSPF with trustworthiness and CPK-based security authentication to achieve a secure state routing protocol.Through simulation verification and analysis,the effectiveness of SLSRP is demonstrated,proving its ability to promptly detect changes in node trustworthiness during network attacks,thereby selecting safer and more trustworthy paths for information transmission.
