Hardware intrusion detection system
An apparatus for intrusion detection includes processing circuitry, a switch, signal detection circuitry, and an analog-to-digital converter (“ADC”). The processing circuitry is coupled to send a challenge signal to a device when the device is coupled to the processing circuitry. The switch is coupled to be enabled and disabled by the processing circuitry. The switch is for coupling to the device to receive a response signal in response to the challenge signal sent by the processing circuitry. The signal detection circuitry is coupled to receive the response signal in via the switch, when the processing circuitry enables the switch. The ADC is coupled to take measurements of the signal detection circuitry at a first output. The processing circuitry is coupled to the ADC and configured to analyze whether an intruder is present in the device based on the measurements of the signal detection circuitry.
