Abstract

Se describen diversas técnicas relacionadas con verificar una distancia entre dispositivos. Una distancia entre dos dispositivos puede ser verificada al requerir que uno de los dispositivos tome una o mas acciones que generan un resultado que solo es posible si el dispositivo está como máximo a una distancia dada del otro dispositivo. En algunos aspectos se logra el intervalo verificado a través del uso de una senal de intervalo y una senal de respuesta. En algunos aspectos la senal de intervalo puede comprender una secuencia aleatoria, seudo aleatoria o determinística. Un dispositivo de respuesta puede operar en una senal de intervalo de acuerdo con una funcion conocida para generar una senal de respuesta. Un dispositivo de intervalo también puede ejecutar operaciones para determinar la probabilidad de que un dispositivo de respuesta operado apropiadamente en una senal de intervalo que el dispositivo de intervalo transmitido al dispositivo de respuesta.Various techniques related to verifying a distance between devices are described. A distance between two devices can be verified by requiring that one of the devices take one or more actions that generate a result that is only possible if the device is at most a given distance from the other device. In some aspects the verified interval is achieved through the use of an interval signal and a response signal. In some aspects the interval signal may comprise a random, pseudo-random or deterministic sequence. A response device may operate on an interval signal in accordance with a known function to generate a response signal. An interval device may also perform operations to determine the probability that a response device operated properly on an interval signal than the interval device transmitted to the response device.
