Course Overview

Technical workshop on quantum-safe archive integrity for broadcast archives, film preservation, and cultural heritage collections. Covers hash-based signature schemes (XMSS, LMS, SLH-DSA) for long-term document integrity, cryptographic timestamping under PQC, OAIS reference model integration, and migration strategies for 50-100 year retention obligations.

Curriculum

Course content is structured into sessions below. Each session is configurable to your organisation's environment, threat model, and objectives.

# Session Topics
1 Archive Cryptographic Dependencies Where asymmetric cryptography sits in digital preservation
2 Hash-Based Signature Schemes for Long-Term Integrity XMSS, LMS, and SLH-DSA for archival contexts
  • Stateful hash-based signatures (XMSS RFC 8391, LMS RFC 8554): security guarantees, state management complexity, and maximum signature counts for archival workloads
  • SLH-DSA (FIPS 205): stateless hash-based signatures eliminating state management risk, with trade-offs in signature size (~8-17 KB) and signing speed
  • ML-DSA (FIPS 204) versus SLH-DSA for archive integrity: lattice-based speed advantage versus hash-based conservative security assumption for multi-decade retention

3 Cryptographic Timestamping and OAIS Integration Re-stamping and preservation metadata under PQC
  • RFC 3161 timestamp authority migration: transitioning TSA signing keys to PQC algorithms and re-stamping existing timestamp chains without breaking validity
  • OAIS reference model mapping: integrating PQC signatures into Archival Information Package structure, fixity checking, and Preservation Description Information
  • PREMIS metadata: recording algorithm transitions, re-signing events, and maintaining cryptographic provenance chains across preservation system migrations
4 Re-Signing Strategies at Scale Migrating existing collections with millions of objects
  • Batch re-signing architecture: parallel signature generation, hash tree approaches, and incremental migration for collections exceeding 10 million objects
  • Hybrid signature strategies during transition: dual classical+PQC signatures maintaining backward compatibility with existing verification infrastructure
  • Fixity verification during migration: ensuring no integrity loss during the re-signing process and maintaining audit trails
Break
5 Regulatory and Standards Landscape ETSI, eIDAS, and national archive requirements
  • ETSI TS 119 312 (cryptographic suites for electronic signatures): PQC algorithm adoption timeline and transition requirements
  • EU eIDAS trust services: qualified electronic signature and qualified timestamp requirements under PQC transition
  • UK National Archives digital preservation policy and NIST SP 800-227 (PQC migration guidelines) applicability to cultural heritage
6 Migration Planning Workshop Building your archive PQC migration roadmap
  • Prioritisation framework: highest-risk collections first (legally significant, evidential, long-retention), then systematic migration of remaining holdings
  • Vendor landscape: archive management system PQC readiness (Preservica, Archivematica, Rosetta) and timestamp authority PQC migration paths
  • Budget and resource estimation for re-signing operations at your collection scale
