Video distribution, long-term archives and content provenance with post-quantum crypto
A national TV archive holds content from the 60s-70s still relevant and valuable. Premium streaming uses breakable classical DRM. In the deepfake era, frame-level authenticity must be mathematically provable (C2PA, Content Authenticity Initiative). RSA signatures in C2PA manifests today will not survive Q-Day — a future deepfake could forge provenance. PosQuantum offers a PQC stack for media: streaming, archive, and provenance with ML-DSA signatures.
Three scenarios where PosQuantum acts
National TV archive (50+ years)
European public broadcaster with 1.6 PB archive (MXF, ProRes, DCP). Historical content, documentaries, children's programs. Redistributed via OTT streaming and international licensing.
Current LTO archive with RSA-2048 signatures in MXF manifests. Q-Day breaks signatures — loss of authorship and chain-of-custody proof.
PUCE Archive with versioned signerKeyId (Ed25519 today, Dilithium3 on upgrade). Read-only migration mode: each asset gets a new PQ signature without changing the original payload. Copyright audit trail remains verifiable.
OTT streaming with Player SDK
2.8M-subscriber streaming platform. HLS/DASH delivery with token-based signing. Premium content (films, series, live sports).
JWT tokens with ECDSA. An attacker can forge tokens post-Q-Day and serve premium streams without paying. DRM (Widevine/PlayReady) depends on today's classical certificate chains.
PUCE Stream (cyan accent in portal) with TTL-PQC tokens. Embeddable Player SDK (iframe or drop-in JS) validating ML-DSA-44 signatures locally. PUCE Archive manifest signing proves original content (anti-piracy).
Content provenance (C2PA) in journalism
European news agency publishing 3,200 photos/videos/day. Adhering to Content Authenticity Initiative (C2PA) to combat deepfakes.
C2PA manifest v1.3 allows RSA / ECDSA — signatures will not survive Q-Day. A photo published today may have forged provenance in 2035.
PQSL Enterprise with ML-DSA-44 (compact, < 3 KB signature) in every C2PA manifest. Camera → editing-suite → CMS: end-to-end signed pipeline. C2PA v2 compatible (PQ algorithms roadmap).
Reference architecture
1. Ingest
Camera / drone / mobile device with PQSL SDK signs each asset at capture.
2. Edit / CMS
PQSL middleware (Express/Fastify) protects CMS API; C2PA manifest regenerated per edit.
3. Archive
PUCE Archive for master files (50+ year retention).
4. OTT delivery
PUCE Stream with TTL-PQC token; Player SDK iframe in subscriber's browser.
5. Provenance
Each asset keeps PQ-signed C2PA manifest — verifiable by any publisher.
