Domain isolated processing for coalition environments

A first cryptographic communication system comprising:

• a common hardware module configured to receive local cryptographic signals and coalition cryptographic signals comprising:
• a receiver;
• a transmitter;
• a common router;
• a data loader communicatively coupled to the common router;
• and
• a trusted router;
• a local cryptographic assembly configured to process the local cryptographic signals, comprising:
• a local end cryptographic unit communicatively coupled to the common router;
• a local cross domain guard communicatively coupled to the local end cryptographic unit and the trusted router;
• and
• one or more local general purpose security modules communicatively coupled to the local cross domain guard;
• a coalition cryptographic assembly configured to process the local cryptographic signals, comprising:
• a coalition end cryptographic unit communicatively coupled to the common router;
• a coalition cross domain guard communicatively coupled to the local end cryptographic unit and the trusted router;
• and
• one or more coalition general purpose security modules communicatively coupled to the local cross domain guard;
• a data recording module communicatively coupled to the data loader comprising:
• a local data recording device;
• and
• a coalition data recording device;
• wherein the first cryptographic communication system is configured to operate within a cryptographic communication network comprising a second cryptographic communication system.
