Parameter sets
| Parameter set | Level | pk (B) | ct (B) | pk+ct (B) | Keygen | Encaps | Decaps |
|---|---|---|---|---|---|---|---|
| BAT-257-512 Note | 1 | 521 | 473 | 994 | 4.59 ms | 4.4 µs | 19.6 µs |
| BAT-769-1024 Note | 5 | 1,230 | 1,006 | 2,236 | 26.75 ms | 7.4 µs | 38.0 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
- Note (all parameter sets): Compact NTRU-based KEM (Fouque, Kirchner, Pornin, Yu; TCHES 2022) with notably small public keys and ciphertexts. A research design — not submitted to NIST or ISO. The two real security levels are shown; the BAT-128-256 toy set is omitted. Sizes are the encoded (transmitted) byte lengths and the timings include (de)serialisation; key generation is NTRU-style and comparatively slow.
