A three-axis taxonomy of QSDC protocols is proposed, classifying them by quantum resource type, physical transmission channel, and device trust model, and it presents a comparative performance analysis of QKD employing a hyperchaotic cipher over QSDC channels across seven quantum image representations, showing that QKD-seeded schemes achieve efficient key distribution, whereas pixel-level security remains dependent on cipher complexity.
