CHIP ACCESS METHOD, SECURITY CONTROL MODULE, CHIP AND DEBUGGING DEVICE

摘要

Some embodiments of the present disclosure provide a chip accessing method, a security controlling module, a chip and a debugging device. A chip accessing method is applied to a chip, including: after a debugging device is detected, triggering security authentication on the debugging device in which a security card that pre-stores a first private key is inserted; acquiring from the debugging device a first authentication information generated by the debugging device at least based on the first private key; determining whether the debugging device is authenticated according to the first authentication information; and enabling a debugging interface when the debugging device is authenticated to allow the debugging device to access the chip through the debugging interface. The embodiments in the present disclosure are advantageous for improving security, convenience, and flexibility when the debugging device is accessing a chip.
