Cyber Diode: Animated 2D Barcodes as a Mobile and Robust Data Diode

The Cyber Diode uses animated 2D barcodes to create ad hoc mobile networks with data diode and robust error correcting properties. It is displayed on a broadcasting device and read by a physically separated receiving device serving as unidirectional optical communication. Data rate and error correction are evaluated. The communication method has beneficial information assurance properties, is well suited for Augmented Reality, and can reduce the cost of sustaining fleets of systems.Cyber Diode use cases are catalogued (including out of band networking for sustainment, device location concealment, and social media privacy infringement and censorship mitigation) and alternate comparable communication methods are reviewed.
