Low-observable encryption device for facilitating communications

A system, comprising:

• a low-observable encryption device, comprising
• an encryption unit configured to encrypt an egressing native packet using an encryption key, create an encrypted egressing native packet, and add a connectionless header to form an egressing connectionless datagram;
• a communication unit configured to couple and communicate with the encryption unit, receive the egressing connectionless datagram, and add a complex header to the egressing connectionless datagram to form an egressing packet;
• a computing unit configured to couple and communicate with the communication unit, establish a communication session between the computing unit and an external computing unit of an external encryption device, transmit an identifier list comprising an identifier, a number of identifiers, and an identifier selecting parameter, select an identifier from the identifier list, receive the egressing packet from the communication unit, and forward the egressing packet to the external computing unit through a path identified from a plurality of paths for a time interval based on the identifier list and the identifier selecting parameter;
• and
• an interchangable device.
