PQ.06 Implementation and Prototype Verification: PQC Hybrid Key Exchange for Base Station/Security Gateway Version 1.0

This document describes a telecom post-quantum use case including the hybrid key exchange solution design, prototype implementation and verification. The work is based on Guidelines for Telecom Use Cases [1], with the following focus:

1. Provide the migration solution analysis for operator’s network, including:
   1. hybrid key exchanges in IPSec/IKEv2 of the base station
2. Test the solution and migration process, including:
   1. hybrid key exchanges in IPSec/IKEv2 of the base station

This document makes recommendations on updates to key negotiation in IKE based on evidence gathered during implementation of the demo.
