[DTCP]
The Digital Transmission Content Protection Specification defines a cryptogrphic
protocol for protecting audio/video entertainment content from unauthorized copying,
intercepting, and tampering as it traverses digital transmission mechanisms such as a
high-performance serial bus that conforms to the IEEE 1394-1995 standard. Only
legitimate entertainment content delivered to a source device via another approved copy
protection system (such as the DVD Content Scrambling System) will be protected by
this protection system.
[Three cryptographic Keys]
•
Authentication Key which is formed as a result of authentication and used to protect the
exchange keys.
•
Exchage Key which is used to set up and protect content streams.
•
Content Key which is used to encrpt the content being exchanged.
