Abstract

Un método para proteger una clave de dispositivo en un dispositivo que comprende al menos un elemento seguro conectado localmente a al menos una memoria programable de un solo uso que almacena un valor global en la forma de una cadena de bits que comprende bits bloqueados y bits desbloqueados. Los bits bloqueados se pre-programan irreversiblemente en la memoria programable de un solo uso durante la fase de inicialización del dispositivo mientras los bits desbloqueados que permanecen en un estado inicial pueden ser programables por el elemento seguro. El elemento seguro se configura para generar, en la inicialización del dispositivo, un valor específico del dispositivo al utilizar el valor global, programar el valor específico del dispositivo previamente obtenido en la memoria programable de un solo uso, y cancelar el valor global al programar los bits desbloqueados de la cadena de bits correspondiente. Un objetivo adicional de la exposición incluye un dispositivo configurado para llevar a cabo el método.
