Fault Injection Attacks Against zkSTARKs

본문 미리보기

Fault injection attacks on zero-knowledge (ZK) constructions have received little attention in the wider literature. Recent work has demonstrated single-fault key recovery attacks against a ZK signature scheme. In this paper, we detail candidate fault injection attacks against zero-knowledge scalable transparent argument of knowledge (zkSTARK) provers, designed to violate ZK capabilities. zkSTARK proving systems are complex, and implementations differ substantially in their implementation specif
