ANSI/SCTE 41 2011
This standard defines the characteristics and normative specifications for the system that prevents unrestricted copying of such high value content as it crosses the POD-Host interface. This standard provides methods for authenticating Host devices, for binding POD modules to Host devices including Diffie-Hellman key exchange, for copy protection key generation, for rescrambling high value content to protect against unauthorized copying (after the POD module employs the conditional access system to descramble it) and then descrambling by the Host, and for transmission and authentication of Copy Control Information.
