Abstract

ÚLTIMA LINHA DE DEFESA ASSEGURANDO E REFORÇANDO CàDIGO ATUAL/SUFICIENTEMENTE VÁLIDO. Trata-se de um computador que é adaptado para auto-validação usando um circuito de validação ou processo dedicado. O circuito de validação pode incluir um circuito de tempo para ativar o processo de validação, um circuito de verificação para verificar se o computador está de acordo com um conjunto predeterminado de condições e um circuito de reforço para impor uma sanção ao computador quando o computador for encontrado em um estado não condizente. O circuito de validação pode incluir conjunto de circuitos criptográficos ou processos para fazer verificação e verificação de assinatura digital. O circuito de validação, de preferência, é pequeno e portátil para ajudar a assegurar que o circuito de validação, em si, não está vulnerável a um amplo ataque. Um método de auto-validação para uso por um computador também é descrito.
