Abstract

DISPOSITIVO PROCESSADOR DE DADOS, SISTEMA DE PROCESSAMENTO DE DADOS E MéTODO DE PROCESSAMENTO DE DADOS EXECUTADO EM UM DISPOSITIVO PROCESSADOR DE DADOS. Compreendendo um dispositivo processador de dados criptografa dados confidenciais que os transforma em dados criptografados, e os grava em uma mídia de gravação predeterminada, bem como decripta os dados criptografados gravados na mídia de gravação, transformando-os novamente nos dados confidenciais; ao efetuar a criptografia, são gerados um algoritmo e uma chave a serem utilizados na criptografia, mediante a utilização de soluções que são geradas seqúencialmente pela atribuição de soluções anteriores a um algoritmo gerador de soluções. As soluções são apagadas quando deixa de ser necessário voltar a atribuí-las ao algoritmo gerador de soluções.
