Paper

https://eprint.iacr.org/2026/835

Alexander Dalton zkSTARKs Fault Injection

Dalton et al. present the first systematic exploration of fault injection attacks against zkSTARK provers, aiming to violate zero-knowledge properties, filling a gap in fault injection research for general-purpose ZK proving systems.

Notes

Fault injection attacks on zkSTARK provers can compromise zero-knowledge properties.
First exploration of fault injection in general-purpose ZK proving systems.
Implementation diversity of zkSTARKs broadens the attack surface.
Proposed multiple attack methods targeting different algorithmic primitives.
Vulnerabilities could undermine privacy guarantees of ZK proofs.
Developers should incorporate fault injection countermeasures in prover implementations.

What is a fault injection attack?

A fault injection attack introduces errors into computation (e.g., via voltage or timing glitches) to break correct execution and potentially leak sensitive information.

How can fault injection affect the zero-knowledge property of zkSTARKs?

By disrupting the proving process, attackers can cause abnormal intermediate values that may leak information intended to remain hidden, breaking zero-knowledge.

Why are zkSTARKs particularly exposed to such attacks?

zkSTARKs are complex, involving components like FFTs, commitments, and low-degree tests. Faults can be injected at different stages, increasing the attack surface.
