ECDSA Under Attack: Lattice Sieving and Fourier Analysis

I stumbled upon this research... https://eprint.iacr.org/2024/296 The author was able to uncover the private key using multiple signatures with less than 4 bits of nonce leakage. My issue is that I don't have the k nonce. There's zero leakage. I don't know the private key or the original message used. So, I tweaked the script a bit. If it takes under 4 bits of nonce leakage to find the private key, I figured I could somehow 'leak' the 6 bits of the k nonce. I'm planning to test every possible pattern (my script will run through all 262,144 combinations). Just to note, I'm using only CPU and it should take about 22 hours to go through everything. I've been trying to follow the approach laid out in the research as closely as possible. What I'm curious about is why you think my method might not work? Where could I be messing up in my code? Thanks a lot. I really value your thoughts. P.S. I've taken out some library imports to keep it clearer.

I was warn about this yesterday. I totally forgot about it when i was coding. thank you so much for the reminder. I appreciate it.

I made some adjustments to the code, but there are small nuances with the selection of signatures

Code find privkey ?

to test if the script is functional there are 3 signatures with the k nonce of just 20 bits. r =  0x6f007fe0bc2a1a0f6d944b8d4a2353e48833e1f6be178f87f293068b25d6d96e s =  0xea5459e9fb80101fbc261b90c59bf20dc497f5f71c90356c9530d035d32bd023 z =  0x840131231b57268049ccbd6b2c84408251b935cb951c069ecb86cf8d4755bf34 k =  0xb37b1 r =  0xdc52f02499d8859b4be4a517898e23f42bd409d5d1ef0f9e49edf775c49aab93 s =  0x120e526332349b7ebe20565240feeb224ed1f0886990d70513a83cb6d941c648 z =  0xa4075d10756be846ad1156e878de2d43b8585e3baf7617b1f164e4c52956419 k =  0x9d59 r =  0xb52b260367f658f3527bfca721358daaa8a115d9566ba966ffdff77e103fd6b1 s =  0x1e7454c7321b93e0c8b85bfdc5801a2e0f29dd62724c3cd1b26a699a486661c5 z =  0xbd0636aac51faf14a7d3439ea4abd1d28095f2836e95d5eea3fbe68a4baaee52 k =  0x2a78a private key; 0x1a838b13505b26867 pubkey: 0430210c23b1a047bc9bdbb13448e67deddc108946de6de639bcc75d47c0216b1be383c4a8ed4fa c77c0d2ad737d8499a362f483f8fe39d1e86aaed578a9455dfc
