Abstract:
Measurement methods, devices and systems based on a trusted high-speed encryption card are disclosed. One of the methods includes: a BIOS actively measuring at least one firmware in a device if an integrity measurement result made by a trusted security chip for the BIOS indicates that the integrity thereof is not corrupted; loading one or more firmware if the integrity of the one or more firmware in the device actively measured by the BIOS is not corrupted; and forbidding a system of the device from being started or controlling the system to enter into a non-secure mode if the integrity of one or more firmware in the device actively measured by the BIOS is corrupted.
