Abstract

Una primera unidad de comunicación (101) comprende: un procesador (203) que obtiene el material de código local que define una primera función de generación de código de una Tercera Parte Confiable (TTP). Un procesador de identidad (205) que obtiene una identidad para una segunda unidad de comunicación (103 y un generador de código (207) determina un primer código criptográfico de la primera función de generación de código en función de la identidad. Un generador (209) genera, en forma local, un valor de perturbación que no es únicamente determinado por los datos que se originan a partir de la TTP. Un modificador de código (211) determina un código compartido criptográfico aplicando el valor de perturbación al primer código criptográfico. La segunda unidad de comunicación (103) también obtiene datos de modificación de código y los utiliza para determinar un código criptográfico para la primera unidad de comunicación (101). Entonces, esta genera los posibles valores del valor de perturbación, y de manera subsiguiente, los posibles códigos criptográficos compartidos. Entonces, selecciona uno que coincida con los datos criptográficos de la primera unidad de comunicación (101). El valor de perturbación podría proporcionar un aumento en la resistencia contra los ataques de colusión.
