# Homomorphic Encryption Kernel Latency on HE Kernels N=2^16 Source: [Homomorphic Encryption Kernel Latency on HE Kernels N=2^16]() Collection index: [llms.txt]() Data updated: 2026-04-07T09:09:58.959Z Evaluation of fundamental Homomorphic Encryption (HE) kernel latencies (Add, Multiply, Rescale, Rotate) measured in microseconds (μs) using the HE Kernels dataset subset containing N=2^16 elements. 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 | Homomorphic Encryption Kernel Latency | | Dataset (including any stated split) | HE Kernels N=2^16 | | Metric | HE Add Latency (μs) | | Unit | TIME | | Direction | Lower is better | | Results loaded | 38 of 38 | | 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 - [HE Add Latency (μs)](): Lower is better; unit: TIME. - [HE Multiply Latency (μs)](): Lower is better; unit: TIME. - [Rescale Latency (μs)](): Lower is better; unit: TIME. - [Rotate Latency (μs)](): Lower is better; unit: TIME. ## Recorded results | Method | HE Add Latency (μs) | Result date | Report paper | | --- | --- | --- | --- | | CROSS | 3.5 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 3.5 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 3.6 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 4 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 5 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 5.6 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 5.7 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 5.9 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 6.3 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 6.5 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 6.5 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 6.6 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 6.8 | Not recorded | 68fa77be1e209131cea75114 | | BASALISC | 8 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 8.2 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 8.8 | Not recorded | 68fa77be1e209131cea75114 | | CraterLake | 9 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 10.9 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 11 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 11 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 13.1 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 13.6 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 14 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 14.5 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 14.9 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 15 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 15.5 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 15.8 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 17.6 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 18.6 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 19 | Not recorded | 68fa77be1e209131cea75114 | | FAB | 40 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 42.8 | Not recorded | 68fa77be1e209131cea75114 | | Cheddar | 48 | Not recorded | 68fa77be1e209131cea75114 | | FIDESlib | 51 | Not recorded | 68fa77be1e209131cea75114 | | WarpDrive | 61 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 79 | Not recorded | 68fa77be1e209131cea75114 | | OpenFHE | 15390 | Not recorded | 68fa77be1e209131cea75114 | ### CROSS HE Add Latency (μs): 3.5.
