Operators protect their own networks, and every other sector depends on those networks. 5G-AKA still relies on a symmetric subscriber key, but 5G added public-key mechanisms that 4G never had, most visibly SUCI identity concealment. Roaming interfaces, SIM provisioning and interconnection agreements all depend on cryptography. Standards bodies are writing the 6G standards now, and their architecture choices will apply for the next decade.
The overview follows GSMA post-quantum guidance and suits network security architects, core and radio engineering leads, and standards staff. Equipment vendors use it to see what their customers are about to require. In the intensive, you map your 5G core, radio, transport and subscriber estate and leave with a sequenced migration plan. We teach both courses from the Telecommunications Extension of the Applied Quantum PQC Migration Framework.
