Abstract

El objetivo de la presente es confrontar con patrones un módulo de seguridad con uno o varios aparatos principales, en un entorno en el que el módulo principal no tiene ningún enlace con un centro de gestión. Este objetivo se alcanza por medio deun método de control de confrontación con patrones entre un primer dispositivo, como un módulo de seguridad amovible, y un segundo dispositivo, como un aparato principal, esta confrontación con patrones consistiendo en proteger el intercambio dedatos gracias a una clave de confrontación con patrones única, dicho método consistiendo en: verificar la confrontación con patrones entre ambos dispositivos y utilizar la clave de confrontación con patrones única, siempre que se haya efectuado laconfrontación con patrones previamente, en el caso contrario; buscar una posición libre entre las posiciones reservadas a los datos de confrontación con patrones en el primer dispositivo y en caso afirmativo; iniciar un procedimiento deconfrontación con patrones transmitiendo un criptograma contenido en el segundo dispositivo, y que contiene un identificador propio a este dispositivo, siendo encriptado dicho criptograma por una clave secreta común a todos los primerosdispositivos; desencriptar con el primer dispositivo este criptograma y extraer el identificador del segundo dispositivo; generar una clave de confrontación con patrones basada en este identificador; memorizar en el primer dispositivo los datos deconfrontación con patrones con el segundo dispositivo.
