Power electronic circuit containing a hardware Trojan

The goal of the project is to design and fabricate a power electronic circuit contains a hardware Trojan.

=Problem Definition= We first found a power converter circuit and became familiar with its construction and the components in the circuit. Once we knew the circuit inside out, we started to simulate it on the computer, looking at its current, voltage, and power characteristics, so that we could find a way to destroy the circuit. When we find the right way to destroy the circuit and the right place to hide our destruction point, we first simulate the results on the computer, then buy the necessary circuit components, and then build the circuit on the board, to conduct real experiments. There are two key points to this project. One is how to destroy the circuitry. Is it permanent or temporary? Was it silent destruction or an explosion in the circuit caused by too much power? The other is how to hide the point of destruction. Do you make it as small as possible or do you use camouflage like animals in nature? These are all things that need to be explored.In this project, we specifically studied the buck converter circuit and the boost converter circuit.

=Background= With the development of electronic technology, network security becomes more important. However, hardware security is also significant. Now most of the technology is inseparable from chips, IC circuits, data storage, and so on. The protection of the high-end technology of these electronic equipments and the security problem of the data are also increasingly prominent. The big electronics companies don't want the results of their research to get out, so they do their best to protect their products. Nevertheless, there are times when electronics companies can not protect their products, so they will destroy them if they have to. The project focuses on how to build an electronic circuit and have it destroy itself if needed.

Introduction
This circuit is called a boost converter or a step-up converter because the output voltage is large than the input. This is another switching converter that operates by periodically opening and closing an electronic switch. A boost converter circuit was choose with a frequency of 120kHz. The purpose is to increase the voltage input from 5V to an output of 12V.

Selective component








Testing and Verification
The figure shown on the left is the voltage change at the output resistor when the circuit is working properly. The figure on the right is the output after changing the switching frequency. The voltage has reached 90V. So the load does not work properly because it is high and runs the risk of damage to the circuit.





Introduction
This circuit is called a buck converter or a step-down converter because the output voltage is less than the input. This is another switching converter that operates by periodically opening and closing an electronic switch. A buck converter circuit was choose with a frequency of 120kHz. The purpose is to reduce the voltage input from 12V to an output of 5V.
