If you go wireless the only security during transmission will be that which is supplied by the content vendor... encrypted files.

Until the download is completed to the device(DigE)... the encrypted files and keys are in separate state.

This would be the case for wire or wireless....links between devices are vulnerable...the shorter the better.

Thing about the TDL....it decrypts the files before transmitting them to a device.

At least with the APS method....the files stay in their encrypted state right down to the end device(DigE). There`s still a separate key issue during the transmission process.

IMO...That is the reason that I feel that MOS is involved at the very encoding of content as well as just after the files are encrypted. Providing added proprietary file security of both the encrypted files and keys as separate items in separate directories....allowing added security to cross distribution links.

If someone snags the separate files during a transmission....they need MOS first to open the separate directory files to get to the keys and encrypted files.

The only way to gain access to the secure MOS directory files is through the automated process within the DigE.

No one touches the MOS key to un lock secure directories.

Once the files are placed within the hardware encryption through their I/O authentication process....there`s no getting them.
