Cong Li, Jibin Sun, Yihao Sun, Chongfeng Xie · 2023
To solve the problem of insufficient address space and secure connection and management of massive terminals in the 5G Internet of Things scenario, this paper proposes an IPv6-based method for terminal authentication in 5G private networks. Firstly, the technical problems in 5G Internet of Things are analyzed. Secondly, an IPv6 based core network side terminal authentication method is put forward, and the system architecture and key methods in this scheme are described, including a novel device identifier generation method, adress configuration method and authentication method. It realizes the verification of unique terminal identification at IP network layer, effectively enhancing the security of terminal access and improving the efficiency of address management. Finally, this paper also analyzes the security properties of this scheme and compares it with other schemes. Analysis results of security among related protocols show that our solution outperforms other related schemes.
