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

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.

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!

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
