Abstract

Patente de Invenção: <B>"CIRCUITO E MéTODO PARA CONFIGURAR E REGISTRAR UM DISPOSITIVO CRIPTOGRáFICO"<D> Um sistema e método para configurar e registrar um dispositivo criptográfico (150). A fase de configuração envolve carregar um número de série do dispositivo (DSER) e uma chave simétrica (SK) dentro da memória não-volátil (215) do dispositivo criptográfico (15). A memória não-volátil (215) está integrada com a lógica de processamento (210) do dispositivo criptográfico (150). O DSER é proporcionado por uma fonte externa, enquanto a SK é gerada dentro do dispositivo criptográfico (150). A fase de registro envolve proporcionar o DSER para um banco de dados (415, 420) que contém a informação criptográfica associada com cada dispositivo criptográfico (150) fabricado. A informação criptográfica inclui pelo menos uma chave pública e uma chave privada encriptada com a SK. O DSER é utilizado para localizar a informação criptográfica apropriada e para transmitir a informação criptográfica para um sistema eletrónico possuindo o dispositivo criptográfico (150).
