Workshop Description
Electronic health record systems were not built with cryptographic agility in mind. HL7 FHIR's interoperability architecture relies on TLS 1.3, OAuth 2.0, and JWT token signing. Every component uses RSA or ECC. A working PQC migration is not a matter of swapping one algorithm; it requires a full dependency map, vendor readiness assessment, and sequenced rollout that keeps clinical systems operational. This workshop provides the methodology to do that, structured around real EHR architecture rather than abstract cryptographic theory. The session includes a facilitator-led cryptographic discovery exercise against a sample clinical data flow, plus a dedicated module on genomic data exposure within EHR cryptographic risk, addressing the NHS Genomics England National Genomic Research Library (110,000+ clinically linked whole genomes) as a specific vulnerability class.
The regulatory pressure is building from multiple directions simultaneously. In the UK, NHS Digital's DSP Toolkit is expected to incorporate explicit PQC readiness requirements by Phase 1 of the NCSC's March 2025 migration roadmap (deadline: 2028). In the EU, NIS2 places hospitals under mandatory risk management obligations enforceable from 2025 with penalties up to EUR 10 million or 2% of global revenue. In the US, HHS has signalled that HIPAA's technical safeguard requirements will be interpreted to include quantum-resistant encryption for long-lived patient data. Participants leave this workshop with a populated cryptographic inventory template, a regulatory gap map for their jurisdiction, a migration sequencing model calibrated to their EHR vendor stack (Epic, Cerner/Oracle Health, MEDITECH, or open-source alternatives), and a NIST CSWP 48 mapping that expresses PQC migration as auditable CSF 2.0 risk outcomes for information governance committees.
