Abstract

"CIRCUITO ELETRôNICO A PROVA DE VIOLAçãO PARA IMPLEMENTAçãO EM UM DISPOSITIVO, DISPOSITIVO IMPLEMENTADO COM UM CIRCUITO ELETRôNICO à PROVA DE VIOLAçãO, E, MéTODOS DE GERENCIAMENTO DE DADOS DE SEGURANçA PARA UM DISPOSITIVO, PARA MANTER SEGURANçA DE DADOS EM RELAçãO A COMUNICAçãO DE REDE ENTRE UM DISPOSITIVO DE REDE E UM PARCEIRO DE COMUNICAçãO EXTERNA, E PARA MARCAR CONTEúDO DIGITAL PRODUZIDO POR UM DISPOSITIVO DE PRODUçãO DE CONTEúDO". A invenção é concernente a um circuito eletrônico à prova de violação (10) configurado para implementação em um dispositivo (100). O circuito eletrônico (10) implementa seguramente e utiliza dados de segurança específicos para um dispositivo durante a operação no dispositivo (100), e é basicamente provido de um segredo armazenado resistentemente a violação (C) não acessível através de uma interface de circuito externo. O circuito eletrônico (10) é também provido de funcionalidade (13) para efetuar processamento criptográfico pelo menos parcialmente em resposta ao segredo armazenado, para gerar uma instância de dados de segurança específicos para um dispositivo que são internamente confinados dentro do citado circuito eletrônico (10) durante o uso do dispositivo (100). O circuito eletrônico (10) é adicionalmente configurado para efetuar uma ou mais operações relacionadas à segurança ou algoritmos (14) em resposta aos dados de segurança específicos para um dispositivo confinados internamente. Deste modo, a implementação segura e utilização de dados de segurança específicos para um dispositivo para fins de segurança pode ser efetivamente obtida. A segurança é descompromissada, uma vez que o segredo armazenado (C) jamais está disponível fora do circuito eletrônico, e os dados de segurança específicos para um dispositivo são internamente confinados dentro do circuito, durante o uso ou operação do dispositivo.
