So you want to deploy FN-DSA
Summary
This article discusses FN-DSA, a proposed post-quantum signature standard. It outlines that the standard does not yet exist (NIST ipd status), explains prehashing challenges, the implications of floating point arithmetic, the possibility of key exposure, and the potential for variable signature sizes. It concludes with a cautious stance: developers should wait for the actual standard before deploying FN-DSA to avoid security regressions.
