Their acknowledgement is because of their conforming to current WAEA...If content providers are willing to provide or allow certain productions on the current format....they`re all set.
Emit....The TDL receives post production encrypted files..with the keys passed forward separate from the encrypted files.
Before the keys are placed within the security of the TDL....they`re in an unprotected state.
The TDL supports three different types of encryption....However, for whatever encryption scheme utilized of the three by a content provider....the key management is still at risk...until it is placed within the TDL.
Files are then decrypted by the TDL...However, this is not the end of the line...it must then pass the unprotected files forward to yet another device..storage device...or end viewing device. The files will sit un protected.
This is not a fully protected end to end scheme...
Wencors model for the management of keys...places them together in a secure environment before they are distributed or passed forward to an on board permanently affixed device...i.e...
TDL...
The keys along with encrypted content stay together....via...hardware encryption on the PDL.(portable data loader)...The keys along with encrypted files are then passed forward together into the DigE hardware encryption scheme....where the files are stored for decrypting and viewing....at the very end of the line.
This is an end to end scheme....no one can readily gain access to the keys or encrypted files throughout the distribution scheme.
There are other fail safes at different layers of the scheme starting at the very encoding of content.
