Abstract

Método de la lectura protegida de una clave cifrada criptográfica (KSe, ) almacenada en una primera memoria (2) de un primer aparato de comunicación (8; 8¿): que incluye los siguientes pasos: a. hacer disponible un primer número predeterminado (PW; X) por el primer aparato de comunicación (8; 8¿) a un segundo aparato de comunicación (6; 13); b. recibir el primer número predeterminado (PW; X) por el segundo aparato de comunicación; c. calcular un código de autenticación de mensaje (MAC) por el segundo aparato de comunicación de un segundo número predeterminado, usando el primer número predeterminado (PW; X) y con la ayuda de una clave predeterminada (K¡, , ); d. hacer disponible el código de autenticación de mensaje por el segundo aparato de comunicación (6; 13) al primer aparato de comunicación (8; 8¿); e. recibir el código de autenticación de mensaje por el primer aparato de comunicación (8; 8¿); f. descifrar la clave criptográfica por el primer aparato de comunicación (8; 8¿), usando el código de autenticación de mensaje como una clave de descifrado.
