The Cool and the Cruel

Code for the paper https://arxiv.org/abs/2403.10328

To run everything, you need

• flatter (only if you want to actually use that, can also reduce with BKZ)
• fpylll
• pytorch (nightly, unless you disable compilation with --compile_bf 0)
• numpy
• tqdm

Note that the data run on in the paper was not produced by this code. However, with data.py one can make smaller datasets in a simplified fashion, see Data.create_new_A and Data.create_data_from_A

main.py: runs the attack, check the file for the options data.py: has methods to create new data (quickly with flatter or BKZ for smaller dimensions) reduction.py: implementation of the reductions, depends on flatter and fpylll. single_worker_attack.py: called by main and has the implementation of the attack.
