Computer systems, methods and program product for multi-level communications

A computer system comprising:

• a first network component located in a restricted access computer sub-system and programmed to include within an unencryptable field other than a payload field within an unencrypted network data packet a code that corresponds with a non-classified coded communication within a library of non-classified coded communications;
• an encryption component located at least in part within the restricted access computer sub-system, connected to the first network component and programmed to encrypt the unencrypted network data packet to provide an encrypted network data packet having the code within the unencryptable field other than the payload field;
• and
• a second network component located at least in part within a non-restricted access computer sub-system connected to the restricted access computer sub-system and the encryption component, and programmed to read the code within the unencryptable field other than the payload field within the encrypted network data packet and select the non-classified coded communication from the library of non-classified coded communications that corresponds with the code.

A method for multi-level communication within a computer system comprising:

• generating within a first network component a network data packet that contains within a field other than a payload field a code corresponding with a coded communication within a library of coded communications;
• transmitting the network data packet from the first network component to a designated second network component connected to the first network component;
• reading within the second network component the code within the field other than the payload field and selecting within the second network component the coded communication from the library of coded communications that corresponds with the code;
• and
• transmitting the selected coded communication from the library of coded communications that corresponds with the code from the second network component to an intended recipient of the selected coded communication.

A method for non-classified communication from a restricted access computer system comprising:

• generating within a first network component within a restricted access computer sub-system an unencrypted network data packet that contains a code within an unencryptable field other than a payload field that corresponds with a coded communication within a library of coded communications;
• transmitting the unencrypted network data packet from the first network component to an encryption component at least in-part within the restricted access computer sub-system;
• encrypting within the encryption component the unencrypted network data packet to provide an encrypted network data packet that contains the code within the unencryptable field other than the payload field;
• transmitting the encrypted network data packet from the encryption component to a designated second network component at least in-part within a non-restricted access computer sub-system connected to the restricted access computer sub-system;
• reading within the designated second network component the code and selecting within the second network component the non-classified coded communication from the library of non-classified coded communications that corresponds with the code;
• and
• transmitting the selected non-classified coded communication from the designated second network component to an intended recipient of the selected non-classified coded communication.

A computer program product for multi-level communication comprising:

• a tangible medium encoded with computer readable instructions to:
• generate, while using a first network component, a network data packet including within a field other than a payload field a code for a coded communication from a library of coded communications;
• and
• select, while using the code within the field other than the payload field within the network data packet, and a designated second network component connected to the first network component, the coded communication from a library of coded communications that corresponds with the code.
