A Trusted Digital Identity Authentication Scheme of Cybertwin

In order to solve the problem of trustworthiness under the Cybertwin network architecture, this paper proposes a trusted digital identity authentication scheme, which constructs the Trusted Identity Platform (TIP) based on the National Network Identity Authentication Platform (NNIA), and innovatively introduces the trusted Cybertwin ID and trusted terminal ID into the IP address to ensure the trustworthiness of the terminal and the Cybertwin. Compared to existing authentication schemes, the scheme in this paper enhances the traceability of the network, effectively protects against man-in-the-middle attacks, and improves the endogenous security of the network. Finally, the challenges of implementing this scheme in large-scale networks are discussed.
