A Comprehensive Survey on Non-Invasive Fault Injection Attacks

Abstract

Non-invasive fault injection attacks have emerged as significant threats to a spectrum of microelectronic systems ranging from commodity devices to high-end customized processors. Unlike their invasive counterparts, these attacks are more affordable and can exploit system vulnerabilities without altering the hardware physically. Furthermore, certain non-invasive fault injection strategies allow for remote vulnerability exploitation without the requirement of physical proximity. However, existing studies lack extensive investigation into these attacks across diverse target platforms, threat models, emerging attack strategies, assessment frameworks, and mitigation approaches. In this paper, we provide a comprehensive overview of contemporary research on non-invasive fault injection attacks. Our objective is to consolidate and scrutinize the various techniques, methodologies, target systems susceptible to the attacks, and existing mitigation mechanisms advanced by the research community. Besides, we categorize attack strategies based on several aspects, present a detailed comparison among the categories, and highlight research challenges with future direction. By underlining and discussing the landscape of cutting-edge, non-invasive fault injection, we hope more researchers, designers, and security professionals examine the attacks further and take such threats into consideration while developing effective countermeasures.
