Abstract
A chip capable of authenticating an off-chip debug firmware program and a debug user account is illustrated. The chip runs the secure boot firmware and executes the secure boot process to verify whether the debug firmware program in a signed program loaded from an external storage device may be executed. After the signed program is successfully verified, the chip runs the debug firmware program to execute a debug user authentication algorithm in the signed program, thereby starting a debug user authentication process. After verifying the debug user account of the external debugging tool connected to the chip is a valid debug user account, the debugging tool is allowed to use the debugging function in the chip according to the authority of the debug user.
