US Patent 11601277 Domain isolated processing for coalition environments

A first cryptographic communication system is disclosed. The first cryptographic communication system includes a common hardware module configured to receive local cryptographic signals and coalition cryptographic signals that includes a transmitter, a receiver, a common router, a trusted router, and a data loader. The first cryptographic communication system further includes a local cryptographic assembly and a coalition cryptographic assembly each including and end cryptographic unit communicatively coupled to the trusted router, a cross domain guard communicatively coupled to the end cryptographic unit and the trusted router, and a general purpose security module communicatively coupled to the cross domain guard. The first cryptographic communication system further includes a data recoding module communicatively coupled to the data loader that includes local and coalition data recording devices. A cryptographic communication networking is also disclosed that includes the first cryptographic communication system and a second cryptographic communication system.
