Title: Help please. How to run this code for bitcoin ? Post by: COBRAS on March 16, 2021, 10:57:52 PM ECDSA with Partially Known Nonces
https://github.com/malb/bdd-predicate Code was used not understand for me input data I think code can provide interesting experiments. Br. Title: Re: Help please. How to run this code for bitcoin ? Post by: NotATether on March 17, 2021, 06:58:37 AM I read the source and it looks like this tool is using some kind of lattice attack[1][2] against weak k nonces that aren't "uniformly generated at random" (to quote the paper below)
You won't get great performance out of this though, because it's a CPU implementation with no GPU acceleration. Even the abstract of Breitner and Heninger (2019) (https://www.researchgate.net/publication/336437771_Biased_Nonce_Sense_Lattice_Attacks_Against_Weak_ECDSA_Signatures_in_Cryptocurrencies) says they only computed hundreds of bitcoin private keys with this software so obviously the speed is not great (in the millions/second range that we are all used to).
