Workshop Description

DRM systems protect content through a multi-layered trust chain that depends heavily on asymmetric cryptography. Widevine licence requests use RSA-2048 for server certificate authentication. PlayReady employs ECC-256 for device certificates. HDCP relies on RSA for authentication across HDMI links. AACS uses ECDSA in the device key infrastructure. Each of these is vulnerable to Shor's algorithm on a sufficiently capable quantum computer. The DRM challenge is that the trust chain spans multiple independent parties (studios, distributors, platform operators, device manufacturers) who must coordinate migration.

This workshop maps the complete cryptographic dependency surface across the DRM ecosystem: content key encryption and distribution (licence servers), device attestation and certificate chains (TEE infrastructure), transport encryption (CENC, CBCS), watermarking integrity, and the standards bodies that govern the specifications (W3C EME, DASH-IF, MovieLabs). For each dependency, we identify the specific asymmetric algorithm at risk, assess the quantum threat timeline based on published estimates, and evaluate the NIST PQC replacement path (FIPS 203 ML-KEM for key exchange, FIPS 204 ML-DSA for signatures). Participants leave with a DRM-specific cryptographic inventory and a coordinated migration strategy that accounts for the multi-party governance reality.

What participants cover

Widevine, PlayReady, and FairPlay cryptographic dependency mapping: RSA and ECC usage in licence delivery, device certificates, and content key hierarchies
HDCP and AACS quantum vulnerability assessment: RSA authentication in HDMI links and ECDSA in disc/device key infrastructure
TEE attestation under PQC: Trusted Execution Environment certificate chains (ARM TrustZone, Intel SGX) and their dependence on classical signatures
W3C Encrypted Media Extensions (EME) and DASH-IF security specification analysis: where PQC changes propagate through the standards stack
Content key hierarchy migration: transitioning from RSA-wrapped content keys to ML-KEM without breaking backward compatibility with deployed device populations
Multi-party coordination strategy: aligning studio, distributor, platform, and device manufacturer migration timelines across the DRM trust chain

Preliminary Agenda

Full-day session structure with scheduled breaks. Content is configurable to your DRM vendor ecosystem, device population, and content distribution architecture.

#	Session	Topics
1	DRM Cryptographic Architecture Where asymmetric cryptography sits in the content protection chain
2	Licence Server and Content Key Vulnerabilities RSA and ECC in Widevine, PlayReady, and FairPlay	Widevine L1/L2/L3 licence delivery: RSA-2048 server certificate authentication, content key wrapping, and device provisioning certificate chains PlayReady device certificates: ECC-256 in the PlayReady Certificate Authority hierarchy and content key protection via AES-128 wrapped by ECC FairPlay Streaming: Apple certificate infrastructure, HDCP enforcement, and content key delivery over TLS with RSA server authentication
Break, after 50 min
3	Transport Encryption and Standards CENC, CBCS, W3C EME, and DASH-IF security	Common Encryption (CENC) and CBCS: AES-128 symmetric encryption is quantum-safe, but key distribution depends on RSA/ECC-protected licence channels W3C Encrypted Media Extensions: CDM interface security model and where PQC changes affect the browser-to-licence-server communication path DASH-IF Content Protection specification: manifest-level signalling of encryption schemes and how PQC migration affects MPD content protection descriptors
4	HDCP, AACS, and Hardware Trust Device-level cryptographic dependencies	HDCP 2.3 authentication: RSA-based locality check and AKE (Authentication and Key Exchange) vulnerability to quantum factoring AACS2 device key infrastructure: ECDSA in the Media Key Block and device certificate revocation implications under PQC TEE attestation chains: ARM TrustZone and Intel SGX remote attestation certificates relying on ECDSA; PQC impact on device provisioning at manufacturing scale
Break, after 45 min
5	PQC Migration Strategy for DRM Coordinating migration across the trust chain	Content key hierarchy transition: ML-KEM (FIPS 203) for key exchange replacing RSA wrapping; ML-DSA (FIPS 204) for certificate signing replacing ECDSA Backward compatibility: hybrid classical+PQC schemes during transition to support deployed device populations that cannot be updated Multi-party coordination: aligning studio (MovieLabs), distributor, platform operator, and device manufacturer migration timelines
6	Watermarking and Content Authentication Non-DRM cryptographic dependencies	Forensic watermarking integrity: cryptographic binding of watermark payloads to content and the impact of PQC on watermark verification infrastructure Content authentication (C2PA/CAI): digital provenance manifests using ECDSA signatures and the transition to PQC-signed provenance chains MovieLabs Enhanced Content Protection and Trusted Device requirements: PQC implications for studio security specifications
7	Q&A and Migration Planning
