ABSTRACT:
A split delay-line oscillator for secure data transmission is disclosed. In one embodiment, an apparatus for a split delay-line oscillator for secure data transmission includes a first modulator/demodulator block in a first device, the first modulator/demodulator block operable to insert a first variable delay to modulate a frequency of a shared carrier signal passing through the first modulator/demodulator block, and a second modulator/demodulator block in a second device, the second modulator/demodulator block operable to insert a second variable delay to modulate the frequency of the shared carrier signal passing through the second modulator/demodulator block, wherein the first and second devices create a shared secret by contributing data on the frequency-modulated shared carrier signal.
