[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.
