Control circuit, electronic device, hardware security protection method, and storage medium

Abstract

This application provides a control circuit, an electronic device, a hardware security protection method, and a storage medium. The control circuit includes: a MCU, a short circuit element, a switch element, and an input/output unit, where a VCC pin of the MCU is connected to a power supply voltage VCC, a GPIO pin of the MCU is connected to an input end of the short circuit element, a GND pin of the MCU is grounded through the switch element, and an output end of the short circuit element is connected to a signal receiving end of the input/output unit; the MCU is configured to output a first control signal through the GPIO pin after the GND pin is grounded through the switch element; and the short circuit element is configured to control, based on the first control signal, the input/output unit to be short-circuited to ground.
