摘　　要：终端直通(D2D)作为5G的关键技术,在5G机动专网上具有广阔的应用前景,但D2D的安全性是该技术面临的重要挑战。本文先分析5G机动专网下的D2D网络架构和面临的安全威胁与需求,提出了一种基于5G-AKA的身份注册、DH密钥交换的身份认证与密钥协商方法,再通过对协议的性能分析,证明该方法可以实现数据机密性和完整性保护,能够有效地抵抗中间人攻击、重放攻击和搭便车攻击等。As a key 5G technology,D2D has broad application prospects on 5G flexible private networks,but the security of D2D is an important challenge facing this technology.Firstly,the D2D network architecture under the 5G flexible private network and the security threats and requirements it faces is analyzed,and an identity authentication and key agreement method is proposed based on 5G-AKA for identity registration and DH key exchange.Then through the performance analysis of the protocol,it is proved that this method can realize data confidentiality and integrity protection,and can effectively resist man-in-the-middle attacks,replay attacks and free-riding attacks.
