Parameter sets
| Parameter set | Level | pk (B) | ct (B) | pk+ct (B) | Keygen | Encaps | Decaps |
|---|---|---|---|---|---|---|---|
| NGCC-1 Implementation findings | 128-bit | 389 | 602 | 991 | 62.16 ms | 25.10 ms | 40.22 ms |
| NGCC-2 Implementation findings | 256-bit | 592 | 882 | 1,474 | 192.48 ms | 72.31 ms | 116.66 ms |

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
- Implementation findings (all parameter sets): Non-canonical field encodings in the submitted code let altered ciphertexts decapsulate to the same key, breaking IND-CCA security (Saarinen). Full findings report(opens in a new tab)
