The invention discloses a safe starting method and related equipment, and the safe starting method comprises the steps: responding to a detected preset safe starting condition, employing a national
root certificate preset in a processor to carry out the trusted measurement of an intermediate
root certificate, and enabling the intermediate
root certificate to be stored in an
external storage space of the processor; when the trusted measurement of the intermediate root
certificate is passed, the intermediate root
certificate is adopted to carry out trusted measurement on an intermediate application
certificate, and the intermediate application certificate is stored in an
external storage space of the processor; when the trusted measurement of the intermediate application certificate is passed, the intermediate application certificate is adopted to carry out trusted measurement on the user certificate, and the user certificate is stored in an
external storage space of the processor; when the trusted measurement of the user certificate is passed, adopting the user certificate to carry out trusted measurement on the basic input / output
system; and when the trusted measurement of the basic input and output
system passes, running the basic input and output
system. According to the technical scheme of the invention, the reliability, credibility and authority of trust chain
verification can be improved.
