Parameter sets
FIPS 186-5 · 3 Feb 2023
| Parameter set | Level | pk (B) | sig (B) | pk+sig (B) | Sign | Verify |
|---|---|---|---|---|---|---|
| P-256 Pre-quantum | Pre-quantum | 65 | 72 | 137 | 22.7 µs | 63.2 µs |
| P-384 Pre-quantum | Pre-quantum | 97 | 104 | 201 | 147.2 µs | 328.7 µs |
| P-521 Pre-quantum | Pre-quantum | 133 | 139 | 272 | 194.3 µs | 365.0 µs |
Wall-clock times vary between runs and machines (CPU frequency scaling, other tenants on cloud VMs); cycle counts are the steadier basis for comparison.
Security flags
- Pre-quantum (all parameter sets): Not quantum-resistant: security rests on classical assumptions only. Listed as a reference point.
Only one version of ECDSA is recorded, so there is nothing to compare yet.
