Attacking Deterministic Signature Schemes Using Fault Attacks

[This paper](https://eprint.iacr.org/2017/1014.pdf) explains the RowHammer Attack is a feasible fault injection attack that can be performed remotely. ECDSA and EdDSA are both vulnerable. The paper recommends using XEdDSA--which is resistant to RowHammer and is secure even when one uses a faulty RNG to generate the nonce.

I thought this paper was worth sharing because it is hard to find a digital signature algorithm that can be resistant to timing attacks and the RowHammer Attack at once.

What I thought was most interesting is that XEdDSA was invented by [Trevor Perrin](https://signal.org/docs/specifications/xeddsa/)\--a notable cryptographer from Signal.
