Fault injection attacks have caused implementations to behave unexpectedly, leading to the extraction of cryptographic keys and the spectacular bypass of security features. Understandably, developers want to ensure the robustness of the software against faults and eliminate during production weaknesses that could lead to exploitation. Several open-source fault simulation tools have recently been released to the public, promising cost-effective fault evaluations. In this paper, we set out to discover how suitable such tools are for a developer who wishes to create robust software. The four fault simulation tools available to us employ different techniques to navigate faults and present varying difficulty levels to the user. We objectively compare the available open-source tools and discuss their benefits and drawbacks.
