Abstract

Un método para detectar una infracción de la velocidad de un vehículo que se desplaza desde un primer sistema de carretera (G1) hasta un segundo sistema de carretera (G2), que comprende: establecer parámetros públicos y privados (g, pG), incluyendo una base de módulo común (pG), de un esquema de cifrado basado en identidad (IBE) en un centro de generación de claves (KGC) y los sistemas de carretera, primero y segundo (G1, G2); capturar al menos un identificador (LPN) del vehículo y una primera marca de tiempo (t) en el primer sistema de carretera (G1) como primeros datos de evidencia (D), utilizar al menos el primer identificador (LPN) y la primera marca de tiempo (t) como una primera identidad para generar una primera clave pública de IBE (PK1,t), cifrar los primeros datos de evidencia (D) con una primera clave de sesión aleatoria (K), cifrar la primera clave de sesión aleatoria (K) con la primera clave pública de IBE (PK1,t), y suprimir los primeros datos de evidencia (D) y la primera clave de sesión aleatoria (K) en el primer sistema de carretera (G1); capturar al menos un identificador (LPN) del vehículo y una segunda marca de tiempo (t) en el segundo sistema de carretera (G2) como segundos datos de evidencia(D), utilizar al menos el segundo identificador (LPN) y la segunda marca de tiempo (t) como una segunda identidad para generar una segunda clave pública de IBE (PK2,t), cifrar los segundos datos de evidencia (D) con una segunda clave de sesión aleatoria (K), cifrar la segunda clave de sesión aleatoria (K) con la segunda clave pública de IBE (PK2,t), y suprimir los segundos datos 20 de evidencia (D) y la segunda clave de sesión aleatoria (K) en el segundo sistema de carretera (G2); calcular una relación (V) de las claves públicas, primera y segunda, (PK1,t, PK2,t), modular la base de módulo común (pG), y buscar la relación (V) en una tabla de relaciones (V) pre-calculadas para un conjunto de diferencias de tiempo entre dichas primera y segunda marcas de tiempo (t), conjunto que representa las infracciones de la velocidad, y, cuando la búsqueda es fructuosa: recuperar al menos una clave privada de IBE (SK1, SK2) para al menos una de dichas claves públicas de IBE (PK1,t, PK2,t) desde el centro de generación de claves (KGC), descifrar al menos una de dichas claves de sesión cifradas (EK) con dicha clave privada (SK1, SK2), y descifrar al menos uno de dichos datos de evidencia cifrados (ED) con dicha clave de sesión descifrada (K).
