Summary - X.2013 (05/2025) - Security measures for digital twin federation in smart cities and communities

A digital twin is developed for specific purposes in domains such as manufacturing, transportation, energy and safety. It 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.
A digital twin federation may face security threats such as a system denial of service, data tampering, distributed denial of service attacks, illegal data sharing, authority upgrading, etc. Sending illegal instructions or malicious codes to other digital twin systems through the DTF could seriously affect the security and operation of the DTF.
To ensure the security of a DTF, security threats and relevant security requirements specific to DTFs need to be analysed and security measures established.
Recommendation ITU-T X.2013 identifies security threats specific to DTFs, analyses security requirements and thus establishes security measures for DTFs.
