Comparative Analysis of Noise Generated in BGV Homomorphic Encryption: Lattigo vs FHEgen Parameters
Post-quantum cryptography has emerged as a critical field following advances in quantum computing that threaten classical encryption schemes such as RSA and ECC. Fully Homomorphic Encryption (FHE), particularly the Brakerski-Gentry- Vaikuntanathan (BGV) scheme based on the Ring Learning with Errors (RLWE) problem, provides a promising solution for secure computations on encrypted data. A fundamental challenge in BGV implementations is the growth of noise during homomorphic operations, which must remain below a decryption threshold to ensure correctness. This study presents a comparative analysis of noise generation in BGV implementations using two distinct parameter selection approaches: Lattigo's pre-validated generic parameters and FHEgen's automatically generated application-specific parameters. Through empirical measurements using Lattigo v6.1.1, we evaluated five parameter sets across initial noise after encryption, noise expansion during homomorphic multiplication, and overall noise growth patterns. Our results demonstrate that Lattigo N13 achieves marginally lower post-multiplication noise (0.0587 log2 bits, or 4.15% lower in magnitude), though FHEgen achieves substantially higher verified security (210 bits vs. 50-60 bits). However, Lattigo's range of pre-validated parameters (LogN = 12 to LogN = 15) offers greater flexibility for varying computational depths. We conclude that the choice between parameter selection approaches depends on application requirements: FHEgen is preferable for well-defined computational needs with noise optimization priorities, while Lattigo is advantageous when flexibility and extensive validation are critical. This work provides practical insights for FHE practitioners in selecting parameters that balance security, noise management, and computational efficiency. 2025 IEEE. -

Comparative Analysis of Machine Learning Models for Uterine Cancer Prediction Using Clinical and Genomic Data
Uterine cancer prediction accuracy is important in clinical decision-making because it improves the overall chances of patient recovery. Several machine learning models, such as Decision Tree, Random Forest, XGBoost Regressor, and Support Vector Regressor, were explored to determine which is more effective in predicting uterine cancer. Attributes such as mutation counts, diagnosis age, and MSI score, were used for the analysis. The different models were tested using the standard performance metrics such as the Mean Absolute Error (MAE), Root Mean Squared Error (RMSE), and R2 Score. Random Forest showed the highest predictive performance with an R2 score of 0.655, followed by XGBoost regressor, which was relatively close to the R2 score of Random Forest. Support Vector Regressor performed very poorly as the R2 score was negative, implying that the model is not suitable for such prediction. Ensemble-based models, which include Random Forest and XGBoost Regressor, have proven to be more effective in handling medical prediction tasks, and this is because of their robustness and their ability when it comes to handle overfitting. Though model generalizability was affected due to small data size and the absence of hyperparameter tuning. The future work will focus on expanding the dataset, implementing hyperparameter tuning, integrating deep learning, and leveraging explainable AI (XAI). The research has provided valuable insight for clinicians who wish to use machine learning for uterine cancer prognosis. 2025 IEEE. -
