Hi all,
Hi Johannes,
we conducted an evaluation regarding PQC use in IMA last year (see [1]
for all
details) where we also considered the interplay of different PQC
signatures and
file systems (ext4, btrfs, XFS, f2fs).
Thanks for sharing this comprehensive study! There are many nuances in
this research paper!

According to my experiments done so far, for verification speed,
ML-DSA-65 is consistently faster than ECDSA P-384 which is used by
current CentOS/RHEL to sign files in a package.
Regarding performance, similar to Coiby, we found that all variants of
ML-DSA
consistently outperformed ECDSA P-256.
Glad to know ML-DSA is also faster than ECDSA P-256!
To avoid duplicate work: Is either one of you planning on writing
patches for IMA to use ML-DSA and convert the current ML-DSA to also
support HashML? I had done the work on this before and could dig out the
patches again...
