The paper introduces GASHE, a gradient‑aware selective homomorphic encryption scheme that encrypts only those gradient components exceeding a differential‑privacy‑calibrated sensitivity threshold, rather than encrypting all parameters. Building on GASHE, SecureDrive‑FL combines DP‑SGD with this selective encryption to form a closed‑loop DP+HE privacy pipeline for federated driver monitoring. Experiments on a ten‑class distracted driver classification task show that SecureDrive‑FL retains the poisoning resistance of DP‑SGD while also defending against Man‑in‑the‑Middle interception, with only an 8–10% runtime overhead.

HEAT introduces a fine‑tuning method that treats the number of iterations used to approximate nonlinearities in fully homomorphic encryption (FHE) as learnable parameters, allowing them to co‑adapt with model weights. By optimizing iteration counts per nonlinearity, HEAT reduces the required iterations, bootstraps, and overall latency for encrypted GPT‑2 decoding while improving decode agreement. The approach achieves a 3.1× reduction in iterations, a 1.6× reduction in bootstraps, and a 1.4× speed‑up in end‑to‑end latency without changing the model architecture or requiring retraining from scratch.

SecureDrive‑FL combines differential privacy (DP‑SGD) with a novel Gradient‑Aware Selective Homomorphic Encryption (GASHE) scheme to protect federated driver‑monitoring models. GASHE encrypts only gradient components that exceed a DP‑calibrated sensitivity threshold, avoiding full‑parameter encryption. In experiments on a ten‑class distracted driver task, SecureDrive‑FL matches DP‑SGD’s poisoning resistance while also defending against Man‑in‑the‑Middle attacks, adding only 8–10% runtime overhead.
