Abstract: A system for facilitating secure communications accesses a secure element in response to determining that an authorized user operates the system. The system causes a light emitter to emit an output light signal for detection by a second system. The output light signal is emitted according to a predefined field of view, which operates as a constraint to prevent devices outside of the field of view from detecting the output light signal. The system also configures the light detector to detect a second output light signal emitted by a second light emitter of the second system. In response to (i) detection of the output light signal by a second light detector of the second system and (ii) detection of the second output light signal by the light detector, the system enables secure communication between the system and the second system.

Abstract: Wireless communication between two electronic devices may be used to determine a distance between the two devices, even in the presence of an otherwise-disruptive attacker. A wireless receiver system of one device may receive a true wireless ranging signal from a first transmitting device and a false wireless ranging signal from an attacker. The wireless receiver system may correlate the wireless signals with a known preamble sequence and perform channel estimation using the result, obtaining a channel impulse response for the wireless signals. The wireless receiver system may filter the channel impulse response for the plurality of wireless signals by removing at least part of the channel impulse response due to the false wireless ranging signal while not removing at least part of the channel impulse response due to the true wireless ranging signal. The receiver system may perform a wireless ranging operation using the filtered channel impulse response.
