Summary

A digital twin is developed for the specific purposes in each domain, such as manufacturing, transportation, energy, and safety, which is suitable for providing functions and services for each domain, but functional expansion is required to provide services for smart sustainable cities and communities with multiple domains. Digital twin federation (DTF) is a combination of digital twin systems in various fields.

The digital twin federation may face security threats such as system denial of service, data tampering, DDoS attacks, illegal data sharing, authority upgrading, etc. Sending illegal instructions or malicious codes to other digital twin systems through the digital twin federation could seriously affect the security and operation of the digital twin federation.

In order to ensure security of the digital twin federation, security threats and relevant security requirements specific to digital twin federation need to be analysed and the security measures need to be established.

This Recommendation identifies security threats specific to the digital twin federation, analyses its security requirements, and thus establishes security measures of the digital twin federation.
