  2. DTCP= Digital Transmission Content Protection • Method of protecting audiovisual entertainment content over bidirectional digital interfaces on Consumer Electronics (CE) products • DTCP Certificates are used by these devices for link protection to transfer AV content • DTCP Certificates are deployed in millions of devices today: TV’s, STB’s, Game Consoles etc.

  3. Problem & Opportunity • CE devices are becoming more “web-friendly”; and we want to enable web enabled services on them (e.g., HTML5 based media content) • It would be nice to reuse their existing DTCP certificates for authentication and authorization, when requesting services via HTTP over TLS • Easier than deploying millions of new certificates on existing devices!

  4. Proposal • Register new Authorization Data Format to carry DTCP certificates • Use Supplemental Data handshake defined in RFC4680 • Use Authorization Extensions defined in RFC5878 http://tools.ietf.org/html/draft-dthakore-tls-authz-01

  5. Thank You!
