Accurate analysis of single event transients requires benchmarks that incorporate physical design of circuits to capture charge sharing effects. This paper provides case studies to show how design variability impacts single event transient simulations.
Performance benchmarks have been used over the years to compare different systems. These benchmarks can be useful for researchers trying to determine how changes to the technology, architecture, or compiler affect the system’s performance. No such standard exists for systems deployed into high radiation environments, making it difficult to assess whether changes in the fabrication process, circuitry,...
Hardware Trojans pose a difficult threat to hardware systems due to the difficulty in their identification. In many cases, the differences observed between Trojan and Trusted chips can be very small. This research explored the feasibility of using low-precision test equipment in order to identify malicious modifications to circuits programmed to Field Programmable Gate Arrays (FPGAs). Examination...
As fabrication technology scales towards smaller transistor sizes, lower critical charge, and higher operating frequencies, single-event radiation effects are more likely to cause errant behavior in multiple, physically adjacent devices in modern integrated circuits (ICs). In order to increase future system reliability, circuit designers need greater awareness of multiple-transient charge-sharing...
Many experimental hardware Trojans from the literature explore the potential threat vectors, but do not address the stealthiness of the malicious hardware. If a Trojan requires a large amount of area or power, then it can be easier to detect. Instead, a more focused attack can potentially avoid detection. This paper explores the cost in both area and power consumption of several small, focused attacks...
