Abstract

SISTEMA E MÉTODO PARA BLOQUEAR UM TPM SEMPRE LIGADO USANDO UM MONITOR. Um computador pode ficar seguro contra ataque ao incluir um ambiente confiável utilizado para verificar um monitor conhecido. O monitor pode ser usado para determinar uma condição do computador para conformidade com um conjuntode condições. As condições podem se relacionar aos termos de uso, tais como os créditos disponíveis para um sistema "pague para usar", ou que o computador está executando um determinado software, como, por exemplo, uma proteção anti-vírus, ou que periféricos não autorizados não estão anexados, ou que uma ficha requerida se encontra presente. O monitor pode enviar um sinal diretamente ou através do arrtbíente confiável para um circuito de guarda. O circuito de guarda interrompe o uso do computador quando o sinal não é recebido em um dado período de espera.
