With the availability of affordable and ready-to-use hardware, such as the Raspberry Pi Pico [1], performing hardware attacks on embedded devices has become more and more accessible, allowing to conduct security assessments at low cost [2, 3, 4]. One particularly interesting method is the use of crowbars as a glitching mechanism [5]. This method uses a MOSFET circuit is used to perform voltage glitches, which can be found in the ChipWhisperer [6]. Our research interest is to investigate the capabilities of using a Raspberry Pi Pico in combination with a crowbar circuit to performing glitching attacks on embedded devices. To do this, we want to test different types of MOSFETs and understand the extent to which these attacks can be performed at low cost.

The scope of this thesis is as follows:

• Conduct a literature review on existing fault injection methods using crowbar-glitches and low-cost hardware.
• Select appropriate MOSFETs for implementing crowbar-glitches capable of manipulating bus signals.
• Design and assemble a basic hardware setup to perform crowbar-glitch fault injections.
  Experiment with altering data transmission by inducing glitches.
• Document the experimental procedures and initial findings.
