Hi Bernd,

I don't quite see that the attack applies, as our nonces are high-entropy *and* never attacker-controlled.

So my (brief) reading of the paper doesn't suggest that this kills GNS-ECDSA.

My 2 cents

Hi,

reading a recent paper (https://eprint.iacr.org/2023/305) I wonder if this has any impact on GNUnet - especially GNS, which uses ECDSA signatures for PKEY-signed payloads. Do we need to phase out PKEYs and replace them with EDKEYs in the future?

Cheers, Bernd.
