# Homomorphic Encryption Energy Efficiency on HE Kernels Energy Comparison Source: [Homomorphic Encryption Energy Efficiency on HE Kernels Energy Comparison]() Collection index: [llms.txt]() Data updated: 2026-04-07T09:09:59.000Z Evaluation of the energy efficiency improvement factors for fundamental Homomorphic Encryption (HE) operations (Add, Multiply, Rescale, Rotate) measured against a baseline, using the HE Kernels Energy Comparison dataset. 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 Energy Efficiency | | Dataset (including any stated split) | HE Kernels Energy Comparison | | Metric | HE-Add Energy Efficiency Improvement | | Unit | SCALAR | | Direction | Higher is better | | Results loaded | 8 of 8 | | 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 Energy Efficiency Improvement](): Higher is better; unit: SCALAR. - [HE-Mult Energy Efficiency Improvement](): Higher is better; unit: SCALAR. - [Rescale Energy Efficiency Improvement](): Higher is better; unit: SCALAR. - [Rotate Energy Efficiency Improvement](): Higher is better; unit: SCALAR. ## Recorded results | Method | HE-Add Energy Efficiency Improvement | Result date | Report paper | | --- | --- | --- | --- | | CROSS | 2253 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 13.6 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 12.8 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 5.61 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 4.55 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 1.32 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 1.2 | Not recorded | 68fa77be1e209131cea75114 | | CROSS | 0.15 | Not recorded | 68fa77be1e209131cea75114 | ### CROSS HE-Add Energy Efficiency Improvement: 2253.
