Hello,
For an increasing demand, I've created an initial implemention of the
ML-DSA signature scheme for Nettle, which I would like to have any
feedback. The code is available here:
https://git.lysator.liu.se/nettle/nettle/-/merge_requests/68
This is a naive implementation based on Alfred Menezes' lecture[1],
without consulting any other implementation, so aside the caveats
mentioned in the MR description, it might have some issues related to
performance or side-channels; I would appreciate your scrutiny of the
code.
Here are some numbers from the hogweed-benchmark program:
