Multiport content encryption engine

A multiport content encryption engine comprising:

• (a) at least one channel configured to carry data;
• (b) an Authentication and Key Exchange (AKE) processor implemented in hardware and configured to perform authentication with an external device to allow sending and receiving of content between the multiport content encryption engine and the external device;
• (c) a plurality of reformatting plain text nodes, each having an input coupled to a corresponding one of the at least one channel and configured to receive one of a plurality of replicated streams of plain text, reformat the replicated streams of plain text and output a plurality of reformatted plain text streams;
• and
• (d) a Content Encryption Engine (CEE) implemented in hardware and coupled to the AKE processor to receive information indicating authentication of the ciphered text, the CEE having:
• (i) a ciphered text input configured to receive ciphered text,
• (ii) a plain text output coupled to the inputs of the plurality of reformatting plain text nodes and configured to output a plurality of reformatted replicated plain text streams that have been decrypted and reformatted;
• (iii) a plurality of inputs configured to receive the reformatted replicated plain text streams;
• and
• (iv) a plurality of cipher text outputs configured to output a plurality of cipher text streams of different formats;
• wherein the CEE receives the cipher text, outputs the plain text, receives reformatted replicated plain text and encrypts the reformatted replicated plain text to form the plurality of cipher text streams of different formats.

A multiport content encryption engine comprising:

• (a) a selector, having a plurality of inputs and an output, the selector configured to receive a plurality of plain text inputs from a plurality of channels and to select from among the plurality of plain text inputs to be coupled to the output of the selector;
• (b) an Authentication and Key Exchange (AKE) processor implemented in hardware and configured to perform authentication with an external device to allow sending and receiving of content between the multiport content encryption engine and the external device;
• (c) a plurality of reformatting plain text nodes having an input configured to receive a plurality of replicated streams of plain text, reformat the replicated streams of plain text, and output a plurality of reformatted plain text streams;
• and
• (d) a Content Encryption Engine (CEE) implemented in hardware and coupled to the AKE processor to allow authentication of the ciphered text, the CEE having:
• (i) a ciphered text input coupled to the selector and configured to receive ciphered text;
• (ii) a plain text output configured to output plain text that has been decrypted and to couple the plain text to inputs of the plurality of reformatting plain text nodes;
• (iii) a plurality of inputs configured to receive the plurality of reformatted plain text streams from the plurality of reformatting plain text nodes;
• and
• (iv) a plurality of cipher text outputs configured to output a plurality of cipher text streams of different formats;
• wherein the CEE receives the cipher text, outputs the plain text, receives reformatted replicated plain text and encrypts the reformatted replicated plain text to form the plurality of cipher text streams of different formats.
