Abstract: The present disclosure relates to a terminal chip and a measurement method thereof. In an example, a terminal chip includes a computing subsystem and a security subsystem. The security subsystem is configured to measure the computing subsystem. A boot time of the security subsystem is earlier than a boot time of the computing subsystem. The security subsystem includes an integrity verification unit configured to perform integrity measurement on data in a boot process of the computing subsystem.
