Persistent faults mark a new class of injections that perturb lookup tables within block ciphers with the overall goal of recovering the encryption key. Unlike earlier fault types persistent faults re...
One Fault is All it Needs: Breaking Higher-Order Masking with Persistent Fault Analysis
fault attacks masking persistent
2019/1/9
Persistent fault analysis (PFA) was proposed at CHES 2018 as a novel fault analysis technique. It was shown to completely defeat standard redundancy based countermeasure against fault analysis. In thi...
