Evaluation of CKKS Homomorphic Encryption scheme performance specifically for the Rotation operation, measured by Latency and Speedup.

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.

| Scope | Recorded value |
| --- | --- |
| Task | CKKS Rotation (CKKS-Rot) |
| Dataset (including any stated split) | CKKS CROSS |
| Metric | Latency (µs) |
| Unit | TIME |
| Direction | Lower is better |
| Results loaded | 3 of 3 |
| Coverage | All results currently returned for this benchmark |

Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol.

## Metrics

- [Latency (µs)](<https://www.sota2.com/research/sota/ckks-rotation-ckks-rot-on-ckks-cross.md?metric=Latency%20(%C2%B5s)>): Lower is better; unit: TIME.

- [Speedup](<https://www.sota2.com/research/sota/ckks-rotation-ckks-rot-on-ckks-cross.md?metric=Speedup>): Higher is better; unit: SCALAR.
