A Cloud-Edge Collaborative Security Architecture for Industrial Digital Twin Systems

Aiming at the serious challenges faced by the cloud-edge collaboration of digital twin systems in smart factories, a cloud-edge collaboration framework for digital twin systems in smart factories is proposed, and a multi-level integration framework of device side, edge side and cloud side is established. Aiming at the external and internal attacks that cloud-edge collaboration of digital twin system may suffer from, a data security management method based on zero-trust security architecture is proposed. This framework can provide an important theoretical framework for cloud edge collaborative process data security management in digital twin system in smart factory.
