SAT and Neural Network Filters for Misinjections in Fault Attacks↗ (원문, 새 창)

본문 미리보기

A misinjection, an injection that misses the fault form an attack assumes, can make an elimination fault attack discard the correct key. They occur when the attacker has not determined the timing of the device, and a random-delay countermeasure wider than the S-box layer can force them even on one who has. This paper presents a SAT filter that removes misinjections without the secret key, one injection at a time. It models the differential propagation from the injected round to the end of the ci
