Terminal control method and device and terminal

The invention relates to the technical field of terminals, and discloses a terminal control method and device and a terminal. The method comprises the steps that in response to the fact that the terminal is powered on, carrying out first measurement on a to-be-loaded starting program of the terminal, and if the first measurement is passed, enabling the terminal to load the to-be-loaded starting program; and if the first measurement fails, carrying out second measurement on a backup startup program of the terminal, if the second measurement is passed, loading the backup startup program to startby the terminal, and otherwise, stopping starting by the terminal. According to the technical scheme, the to-be-loaded starting program is measured, so that the safety and reliability of the to-be-loaded starting program are ensured, and the starting safety of the terminal is improved. When the to-be-loaded startup program is tampered, a backup mechanism is introduced to measure the backup startup program, so that the su
