Abstract
By comparing a chip unique password, certification for activating a debug function can be established on the chip unique password. Thus, even when the chip unique password is lost due to negligence, not only certification for activating debugging on other motherboards of the same model number can remain unaffected, but also risks caused by replacing a chip or by a private key leakage from a system manufacturer are eliminated.
