Abstract

"MéTODO E SISTEMA PARA ASSEGURAR A CONFIABILIDADE DO DISPOSITIVO ELETRôNICO, DISPOSITIVO ELETRôNICO, E DISPOSITIVO DE ARMAZENAGEM". A invenção relaciona a um método para assegurar a confiabilidade do dispositivo eletrônico (1). Ao menos os primeiros (IDD, A1, CH1) e os segundos (A2, CH2) dados de verificação são armazenados no dispositivo eletrônico (1). No método, o programa de reinicialização é iniciado (501), em cujo programa de reinicialização ao menos o primeiro (P1) e o segundo (P2) passos de reinicializar são executados. No primeiro passo de reinicialização, a confiabilidade de pelo menos o primeiro dado de verificação (IDD, A1, CH1) é examinada, onde se a verificação apresenta que ao menos o primeiro dado de verificação (IDD, A1, CH1) é verdadeiro, o segundo dado de verificação (A2, CH2) relacionado à pelo menos o segundo passo de reinicialização é examinado para confirmar a confiabilidade do segundo passo de reinicialização. Se a verificação apresenta que ao menos o segundo dado de verificação (A2, CH2) relacionado ao segundo passo de reinicialização for verdadeiro, o segundo passo de reinicialização (P2) é executado após o primeiro passo de reinicialização (P1).
