Intrusion Detection and Botnet Prevention Circuit for IoT Devices

摘要

The need for secure and trustworthy devices has become the main question in the Internet of Things market nowadays. This work aims to introduce a circuit connected inline to the device’s power supply and analyze its behavior. The detection circuit operates in real time (Real Time detection), i.e. it collects the information by reading the values of the current intensity from the device and processes it for the detection of abnormal activities. Exploiting side-channel attack techniques, the circuits detect any anomaly of the expected operation and quarantines the device under monitoring. The circuit is analyzed and a simple implementation is depicted. The results of the circuit’s test showed excellent efficiency in intrusion detection, with a 100% success.
