Abstract

Patente de Invenção: <B>"APARELHO E MéTODO PARA RECRIPTOGRAFAR DADOS"<D>. Um dispositivo criptográfico (140) formado como um circuito integrado envolvido em um pacote de circuito integrado. O dispositivo criptográfico (140) decifra informação que tem um primeiro formato criptografado (202), que é introduzida no dispositivo criptográfico, produzindo uma informação em um formato não-criptografado (241). A informação no formato não-criptografado (241) é subseq³entemente recriptografada em um segundo formato criptografado (223), o qual é extraído do dispositivo criptográfico (140). As operações de decifração e recriptografação são realizadas inteiramente no dispositivo criptográfico (140).
