[0395] Content Delivery for In-Flight Entertainment v2.0
[0598] DVD Delivery for In-Flight Entertainment v1.0

     Charter
       “ .. To identify and standardize specifications for the
           distribution of digital entertainment / DVD media to
           In-Flight Entertainment systems.”


     Which
        “ .. Identifies and standardizes several aspects of
            source media, digitization, compression &

  Security Issues Addressed

     Content security for both MPEG-based and File-
      based encryption with 3-DES using RSA public /
      private keys.
     DES (56-bit Key for MPEG-1); 3-DES (56-bit Key for
      MPEG-2); RSA algorithm w/ 1024-bit Keys, Control
      Words, EMM’s, ECM’s, Public / Private Keys,
      Copyright Flags, Secure Facilities, etc.
     Parties: Airlines, Delivery System Provider, &
      Content Provider / Laboratory.
      WAEA Specification 0598
DVD Delivery for In-Flight Entertainment v1.0

Security Issues Addressed

   Early & Late Window Content Rules
   DVD Region Code 8 for IFE (amongst others)
   Security of Special Purpose DVD Drives / Players
   Security Module, 3-DES, 1024-bit RSA, KMAs,
    Device Keys, Private Keys, Key Protection,
    Decryption, Authentication, Fingerprinting, Secure
    Environments, etc.
   Parties: Airlines, Device Manufacturers, KMA’s, &
    Content Providers.
       WAEA Specification 0403
    Digital Content Delivery Methodology for
   Airline In-Flight Entertainment Systems v1.0


 “ .. Scope includes the interfaces, delivery processes,
  security & key management between content point
  of origin and delivery to onboard IFES.”

 Multi-phased approach
      Phase 1 -- completed
      Phase 2 -- about to begin
      Phase 3 -- who knows ??
   WAEA Specification 0403
 Digital Content Delivery Methodology for
Airline In-Flight Entertainment Systems v1.0

“Phase 1” Security & Key Mgmt. Issues
  Security system for MPEG-4 pt. 2, MPEG-4 pt. 10,
   and VC-1 codecs which would encourage the
   provisioning of early-window release content
  Simplification of the content distribution process
   including enhanced automation
   WAEA Specification 0403
 Digital Content Delivery Methodology for
Airline In-Flight Entertainment Systems v1.x

“Phase 2” Security & Key Mgmt. Issues
  Physical &/or Logical Characteristics
      Fixed & Portable Players
      Wired & Wireless Connections
      Airline-provided & Passenger-owned (PAX) Players
      Security to Aircraft by “Tail Number”
   WAEA Specification 0403
 Digital Content Delivery Methodology for
Airline In-Flight Entertainment Systems v1.x

“Phase 2” Security & Key Mgmt. Issues                       (cont.)

  Business Model(s) &/or Legal Issues
   Portable Players [both airline & PAX (or passenger-owned)]
       Who owns them?
       What about security for each portable?
       How do they effect other systems?
       Broadband streaming / downloading to PAX units where
        encrypted keys are transmitted, but not the actual content?
                WAEA 0403
  Drilling-Down into “Phase 2”
Physical &/or Logical Characteristics
  A) “System” Type(s)
      Tape, Disk, IP, Memory-based

  B) “Device” Type(s)
      Fixed – to – Portable Continuum
            (i.e. fixed, portable, hybrid)

  C) “Loading” [or “Transmission”] Type(s)
      Wired – to – Wireless Continuum
            Getting content onto System and Device Types
  D) Security to Aircraft by “Tail Number”
      Content identified per plane
               WAEA 0403
                “Phase 2”


Conclusion:
  One can see the different facets of content
  security which will need to be dealt with during
  Phase 2. Many of these are difficult problems
  which require much thought and collaboration
  among the diverse industries.
