Scripts for exploring SPHINCS+ parameter tradeoffs, computing security levels, signature sizes, and signing/verification costs.
- security.sage computes the security level for FORS and PORS+FP parameter sets
- original-sphincs-parameter-search.sage script from https://sphincs.org/data/sphincs+-specification.pdf (updated for SageMath 9.0)
- costs.sage computes signature sizes and signing/verification times for SPHINCS+ variants
- stateful.sage evaluates stateful alternatives (XMSS, XMSS-MT, SHRINCS/UXMSS) against the SLH-DSA-128s baseline
- octopus_pmf.py computes the PMF of the Octopus authentication set size (MIT license, from https://github.com/MehdiAbri/PORS-FP)
- slhdsa-2to40.sage sweeps SLH-DSA parameter tuples and filters them by security level and signature size
- run_experiments.py runs the full parameter sweep and writes results to CSV
- export_site_data.sage exports
site/data.json, the dataset both site pages load - utils/ helper scripts for searching and visualising the parameter space
- tests/ regression suite, run
python3 tests/test_regression.py - document/ LaTeX source for the accompanying technical report
- site/ interactive explorer hosted on GitHub Pages, stateless parameter search over all report schemes (SPX / W+C / FORS+C / PORS+FP) with worst-case mode, shareable URL state and CSV export (index.html), and stateful scheme comparison (stateful.html). The report PDF is not tracked in git: CI compiles document/ and deploys it as
site/report.pdf(also attached to releases on tags)
