Abstract

The effect of cable capacitance in the classical key distribution system based on resistors and band-limited noise sources is re-examined. Both the lumped element analysis and the transmission line analysis are performed. As long as the cable capacitance and inductance are fully taken into account, the lumped element analysis and the transmission line analysis generate identical results. When the cable is bootstrapped with a driven shield, the capacitance can be neglected, but the transit time should not be overlooked.
