Abstract

La presente invencion se refiere a un circuito para, y método de, generar una clave criptográfica en un nodo de comunicaciones. El circuito incluye: (1) circuitos de comunicaciones para comunicar una primer semilla durante una primer sesion de comunicaciones y comunicar una segunda semilla durante una segunda sesion de comunicaciones temporalmente separada de la primer sesion de comunicaciones y (2) circuitos procesadores para crear la clave criptográfica a partir de la primer y segunda semillas, la comunicacion de la primer y segunda semillas ocurre durante la primer y segunda sesiones de comunicaciones separadas temporalmente, en forma respectiva, para de esta manera mejorar una privacía de la clave criptográfica.
