PQC in Mobile Networks: Insights from the GSMA Task Force
summary
GSMA PQTN-TF (with IBM and Vodafone and 60+ organisations) reports concrete guidance: a crypto bill of materials, NIST-aligned migration timelines and a five-year readiness target. Mobile specifics: eSIM public-key provisioning is already required, 5G’s disaggregated cloud increases attack surface, and legacy risks persist — fake base stations and SMS blaster IMSI-catcher downgrade attacks bypass networks. Operational challenges include key management, signaling (unencrypted SS7), IoT device CPU/battery limits and large-key performance, so recommendations focus on crypto-agility and phased testing.
