摘　　要：针对移动无人驾驶车联网的节点(车辆)易遭受伪装攻击,且应对恶意攻击响应速度较慢的问题,提出一种无人驾驶车联网授权/认证安全加密算法。启用多重验证/加密的方法,在授权证书中添加隐蔽因子,攻击者在破译节点访问证书时会面临更大的困难。为增强协议的安全等级,在授权服务阶段采用临时会话秘钥和双向加密/解密操作来确保授权证书的唯一合法性,提高授权证书的信任等级。安全性分析和仿真对比结果表明,MARS协议可以抵抗多种网络攻击,相比基于新型安全架构的VANET信任及认证协议和高效安全拓扑控制的VANET身份认证协议,MARS协议的开销分别为两种算法开销的18.01%和22.97%。For the problem of the nodes（vehicles）of mobile unmanned driving vehicle networks are susceptible to camouflage attack and slow to respond to malicious attacks,a security encryption algorithm of authorization/authentication for unmanned driving vehicle networks was proposed.The encryption algorithm enabled the multiple authentication/encryption method and a covert factor was added to the certificate,attackers faced more difficulties in deciphering the node’s access to the certificate.To enhance the security level of the protocol,the temporary session key and the bidirectional encryption/decryption operation was adopted in the authorization service phase to ensure the unique validity of the authorization certificate and enhance the trust level of the authorization certificate.Results of security analysis and simulation results show that,MARS protocol can resist denial of service attacks,disguised attacks,tampering attacks and other network attacks,and compared VANET authentication based on a new security architecture VANET trust and security authentication protocols and efficient topology control protocol,MARS agreement achieves overheads of 18.01% and 22.97% of that of the two algorithms.
