⛷️ SQIsign
core properties
- Compact keys and signatures.
- Confident tuning of security parameters.
- Relatively simple and fast verification.
- A complex signing procedure.
sizes
| parameter set | public keys | signatures |
|---|---|---|
| NIST‑Ⅰ | 64 bytes | 177 bytes |
| NIST‑Ⅲ | 96 bytes | 263 bytes |
| NIST‑Ⅴ | 128 bytes | 335 bytes |
performance
Cycle counts for a generic C implementation running on an Intel Ice Lake CPU. Optimizations are certainly possible and work in progress.
