feat(crypto): nistcurves v0.6.0 (shape-2 row gen) — 39.7 s handshake @64 MHz - #61
Merged
Conversation
…hake @64 Bump libs/nistcurves v0.5.0 -> v0.6.0 (issue #71: inline quarter-square row generation in the FP_ONCHIP_MUL profile). No integration changes — wrapper, glue TU, gates, and segment invariants all carry over (og_common $4214, sqtab $BC00 verified). C64U measurements (no-comb verify archive, 4-pt fit residuals <2%): verify 88.3/43.3/30.9/22.9 s at 16/32/48/64 MHz, D=1.1 s, C=1396 MHz*s (-26% vs shape-1); REU-vs-onchip crossover drops ~34 -> ~22 MHz. HTTPS e2e: 51.0 s @48, 39.7 s @64 (from 47.5 s on v0.5.0, 64.7 s on the REU baseline). VICE KAT oracle 3/3.

Delta on top of #60: bumps libs/nistcurves to v0.6.0 (issue #71 — inline quarter-square row generation). Zero integration churn: the wrapper/glue/gates from #60 carry over unchanged; link invariants verified.
Measurements (C64U, no-comb verify archive)
Next lever (not in this PR): comb-archive adoption (
nistcurves-onchip.a+ precompute boot + bank-2 residency) — upstream comb verify is 11.8 s @64, projecting a ~28-29 s handshake.🤖 Generated with Claude Code
