摘　　要：随着飞机与地面系统之间的交互逐步增多,无线通信的安全隐患也逐渐凸显。机载场景涉及到机载设备、航空公司、服务提供商等多个组织,采用基本的密码认证方式已无法保障通信安全,所以提出一种针对机载需求的基于数字证书的空地无线接入认证技术。以空地无线接入认证架构为基础,梳理了涉及的关键技术,主要包括机载无线接入、公钥基础设施和机场网络无线接入认证服务在机载场景中的应用,搭建了一个基于数字证书的EAP-TLS双向认证机制的空地无线接入仿真环境,通过实验验证FreeRadius结合数字证书能够进行有效的身份认证,提高空地间通信的安全性。As the interaction between aircraft and ground systems gradually increases,the security risks of wireless communication also gradually become prominent.The airborne scenario involves many organizations such as airborne equipment,airlines,service providers,etc.The basic password authentication method can no longer guarantee the communication security,so a digital certificate-based air-to-ground wireless access authentication technology for airborne requirements is proposed.Based on the air-to-ground wireless access authentication architecture,this paper summarizes the key technologies involved,including the application of airborne wireless access,public key infrastructure and airport network wireless access authentication service in airborne scenarios,and builds an air-to-ground wireless access simulation environment based on digital certificate EAP-TLS bidirectional authentication mechanism.The experiment verifies that FreeRadius combined with digital certificate can carry out effective identity authentication and improve the security of air-to-ground communication.
