Parameter sets
| Parameter set | Level | pk (B) | ct (B) | pk+ct (B) | Keygen | Encaps | Decaps |
|---|---|---|---|---|---|---|---|
| CMultiURAG-128 Implementation findings | 128-bit | 3,866 | 7,332 | 11,198 | 446.3 µs | 746.7 µs | 1.86 ms |
| CMultiURAG-256 Implementation findings | 256-bit | 10,780 | 15,304 | 26,084 | 951.8 µs | 1.52 ms | 3.74 ms |
| CMultiURAG-512 Implementation findings | 512-bit | 28,866 | 40,926 | 69,792 | 4.15 ms | 5.86 ms | 16.09 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): Malformed ciphertexts crash the submitted reference decapsulation, and ignored padding bits make the 512-bit set's ciphertexts malleable (Saarinen). Full findings report(opens in a new tab)
