Method for establishing trusted environment in power distribution terminal

The invention provides a method for establishing a trusted environment in a power distribution terminal. A trusted chip is added in the power distribution terminal to be used as a hardware trust root, pre-configured integrity reference values are stored inside, and then a secure startup module is added in a system to be used as an initial operation module of the system. During startup of the system, integrity measurements are performed on a system state and a critical system image, so that the integrity of the operation system on the power distribution terminal is protected, trust is established, the trusted operation environment can be established finally, the ability of malicious software to destroy the integrity of the system is restrained from the source, and the security level of the system of the power distribution terminal is increased.
