Convoy_DTN: A Security Interaction Engine Design For Digital Twin Network

A digital twin is a real-time representation of physical assets in a digital world. In future 6G networks, digital twin as the key technology will be widely used in intelligent manufacturing, smart city and scientific research etc., forwarding the whole society towards a "digital twin" world combining virtualization and reality. Just like the real network, the Digital Twin Network (DTN) will also face security risks and various attacks. In the DTN, the wrong instruction distribution from the twin network to physical network will directly affect the real world and cause chaos, so it is necessary to ensure the security of interaction interface. In this paper, we propose a security interaction engine named Digital Twin Protection Function (DTPF) to guarantee the confidentiality, integrity, stability and non-reputation of messages during DTN policy distribution, which can provide a reference for securing the development of DTN.
