Abstract

Patente de Invenção: "DISPOSITIVO DE CODIFICAçãO". A invenção refere-se a um dispositivo de codificação para a realização de uma codificação criptográfica e/ou uma autenticação de acesso com uma unidade de processamento de dados (1, 1'), com uma unidade de desacoplamento (2), com uma interface de suprimento de corrente (SV) e com uma unidade de suprimento de cadência principal (3), onde um gerador de perfil de corrente (4) gera um perfil de corrente (SP2) de tal modo e superpõe a um perfil de corrente (SP1, SP1') da unidade de processamento de dados (1,1'), que impede uma agressão com auxílio de análise de correlação do perfil de corrente.
