Latest Patents

Chapman's notable patent is titled "Characterizing fault injection on power distribution networks with voltage sensors." This patent addresses power and electromagnetic fault injection vulnerabilities in integrated circuits (ICs). It describes a method for characterizing these vulnerabilities by sampling one or more integrated timing sensors in real-time or through equivalent-time sampling. The process involves performing a series of fault injection attempts, where an array of timing sensors captures measures of relative propagation delay that fluctuate with instantaneous voltage. Increased voltage fluctuation can indicate a higher probability of faults in digital logic. The patent also discusses related apparatus, systems, techniques, and articles.
