As may be implemented in accordance with one or more embodiments, a leading edge of one or more pulses in a waveform of a signal is obscured as part of distance-based authentication. For instance, noise may be generated via a noise modulation circuit and combined with some or all of a leading edge of a pulse. Distance-based authentication is provided by transmitting a signal with a waveform having the obscured portion of the leading edge, which operates to mitigate detection of the polarity of the leading edge or otherwise of the leading edge itself."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Communications with distance authentication","description":"Distance-based authentication is provided for mitigating undesirable interaction and/or attacks upon ranging systems, such as those involving vehicle entry or secure payment.
