Abstract
"MéTODO DE VERIFICAçãO DE VALIDADE PARA CóDIGO DE UMA REDE DIGITAL LOCAL". O objetivo desta invenção é propor um método de controle para o ajustamento de um código de rede (CR). Este método é aplicado durante a transferência de dados vindo de uma fonte de acesso condicional para uma rede local. Ele atua na verificação da autenticidade de um código de rede (CR) usando dados de controle relevantes que são fornecidos pelo centro de verificação geralmente na forma de uma lista {(CT)~ CR1~, (CT)~ CR2~, (CT)~ CR3 ...~}. Uma verificação da presença ou ausência de um criptograma (CT)~ CR~ é efetuada de acordo com a lista {(CT)~ CR1~, (CT)~ CR2~, (CT)~ CR3 ...~}. O criptograma (CT)~ CR~ é constituído a partir de um código de teste (CT), fornecido pelo centro de verificação, criptografado por um código de rede (CR) de um módulo de segurança (MT) de um dispositivo (TV1, TV2, PC) conectado à rede.
