Reliable data diode transmission using erasure coding

A cross domain system, comprising:

• one or more processors;
• and
• one or more memories storing computer-executable instructions that, when executed by the one or more processors, cause the cross domain system to:
• receive, by a sender node of the cross domain system, data for transmission across the cross domain system, the data comprising a first number of data segments;
• generate, by the sender node using the data and according to an encoding algorithm, a datagram comprising a second number of data segments, the second number of data segments greater than the first number of data segments;
• transmit, by the sender node, the datagram to a receiver node of the cross domain system using a data diode;
• and
• recover, by the receiver node, the data using at least a portion of the second number of data segments of the datagram.

A non-transitory computer-readable medium comprising executable instructions that, when executed by one or more processors of a cross domain system, cause the cross domain system to:

• receive, by a sender node of the cross domain system, data for transmission across the cross domain system, the data comprising a first number of data segments;
• generate, by the sender node using the data and according to an encoding algorithm, a datagram comprising a second number of data segments, the second number of data segments greater than the first number of data segments;
• transmit, by the sender node, the datagram to a receiver node of the cross domain system using a data diode;
• and
• recover, by the receiver node, the data using at least a portion of the second number of data segments of the datagram.
