A digital subscriber communication terminal includes an adaptive output
interface having a device key set, which, along with a subscriber device
coupled to the adaptive output interface, determines a "shared secret."
The adaptive output interface uses the "shared secret" to encrypt content
and transmits the content to the subscriber device coupled to the
adaptive output interface. The digital subscriber communications terminal
includes a processor, a memory having an encrypted device key set and an
encrypted device key set decryptor stored therein and a secure element
having a key decryptor. The secure element is adapted to receive the
encrypted device key set decryptor and use the key decryptor to decrypt
the encrypted device key set decryptor. The device key set decryptor is
provided to the processor, which decrypts the encrypted device key set
using the device key set decryptor, and the device key set is loaded into
the adaptive output interface.
