Body 
Abstract: This liaison statement informs about the initiation of a new draft
Recommendation Y.cnps: “Service model of attestation-assisted credible network
path provisioning based on orchestration in future networks”.

ITU-T Study Group 13 would like to inform about the initiation of a new draft
Recommendation Y.cnps: “Service model of attestation-assisted credible network
path provisioning based on orchestration in future networks” at the ITU-T SG13
meeting (Geneva, 3-14 March 2025).

This draft Recommendation aims to study the service model of
attestation-assisted credible network path provisioning based on orchestration
in future networks, including the service model concept, general
characteristics, scenario and use cases as well as high-level technical aspect
for supporting the attestation-assisted credible network path provisioning
service.

In addition, another on-going draft Recommendation Y.CCO-req: “Requirements of
orchestration supporting confidential computing for network slices in IMT-2020
networks and beyond” is based on the technique “(remote) attestation” (RFC9334,
RFC9683) for confidential computing.  ITU-T SG13 would like to know the current
treatment of “(remote) attestation” or alternative methods in ITU-T SG17, and
the appropriateness of studying this technique in ITU-T SG13.

ITU-T SG13 looks forward to getting frank opinions, and keeping continued
collaboration and exchanging information with you on this topic.
