Secure delivery of encrypted digital content |
摘要 |
A content decoder is split into a decoder core and remaining portions. The decoder core implements decryption of encrypted content according to a selected encryption scheme, and the remaining portions provide an interface between the decoder core and content presentation systems/devices. Isolating the selected encryption scheme within the decoder core allows the content decoder to be produced and delivered to end users before the encryption scheme has been selected or developed. A logical separation of the content decoder from the decryption core allows the decryption core software to be updated and/or changed as needed.
