Abstract

Se proporcionar un sistema (200) para configurar un dispositivo de red (300) para la compartición de claves, y un primer dispositivo de red y un segundo dispositivo de red (300) configurados para determinar la clave compartida entre los mismos. El sistema comprende un conseguidor de material de clave (210) para obtener en forma electrónica un polinomio de reducción global público (216, N (t)), un primer conjunto privado de polinomios bivariados (212, f.(,)) y un segundo conjunto privado de polinomios de reducción (214, Qi (t)), con cada polinomio bivariado en el primer conjunto que se asocia con un polinomio de reducción del segundo conjunto y una unidad de manipulación de polinomios (220) para calcular un polinomio de clave privada univariado (228) a partir del primer conjunto privado y el segundo conjunto privado al asociar un número de identidad (A) del dispositivo de red con un polinomio de identidad, obtener un conjunto de polinomios univariados por cada polinomio particular del primer conjunto privado, sustituir el polinomio de identidad (A) en el polinomio particular fi(A,) y reducir modularmente al polinomio de reducción asociado con el polinomio particular y sumar el conjunto de polinomios univariados, el sistema está configurado para almacenar electrónicamente el polinomio de clave privada univariado, generado (228, 236) y el polinomio de reducción global público (216, N(t)) en el dispositivo de red. El primer dispositivo de red almacena el polinomio de clave privada univariado (312) y el polinomio de reducción global público (314, N (t)) y su número de identidad (310, A). El primer dispositivo de red obtiene una clave compartida a partir de la asociación del número de identidad de un segundo dispositivo de red con un polinomio de identidad, la sustitución del polinomio de identidad en el polinomio de clave privada univariado y la reducción del resultado de la sustitución modularmente al polinomio de reducción global público (N (t)).
