Abstract

Un aparato de procesamiento de información que almacena datos fiscales en el mismo, incluye un chip que tiene, como una función, generar una clave que se utiliza para cifrar datos en base a los datos fiscales, al menos una función de generar una clave secreta y una clave pública en relación con un método de cifrado de clave pública y una función de cifrar los datos de entrada y que tiene una primera memoria montada sobre el mismo y una unidad de control que almacena una clave secreta generada por la función del chip en la primera memoria; almacena al menos parte de los datos distintos de los datos relacionados con la clave secreta en la segunda memoria diferente de la primera memoria, y almacena la clave pública generada por la función del chip en la segunda memoria diferente de la primera memoria.An information processing apparatus that stores fiscal data therein, includes a chip that has, as a function, generating a key that is used to encrypt data based on fiscal data, at least one function of generating a secret key and a public key in relation to a public key encryption method and a function of encrypting the input data and having a first memory mounted thereon and a control unit that stores a secret key generated by the function of the chip in the first memory; it stores at least part of the data other than the data related to the secret key in the second memory different from the first memory, and stores the public key generated by the chip function in the second memory different from the first memory.
