Authz Extension to use DTCP Certificates in TLS handshake (draft -dthakore-authz- 01)

Proposal to use DTCP certificates for authentication in web-enabled consumer electronics devices, leveraging existing certificates to enable secure content transfers over bidirectional digital interfaces. This draft aims to streamline the authorization process, avoiding the need to deploy new certificates on millions of devices.

  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!
