Machine learning framework enhances QKD security against stealthy attacks

Researchers have developed a novel machine learning framework to enhance the detection of eavesdropping attacks in BB84 Quantum Key Distribution (QKD) systems. This framework moves beyond the traditional fixed QBER threshold by analyzing temporal features of QBER, capturing burst behavior and instability. Evaluated using Random Forest, XGBoost, and SVM-RBF classifiers, the XGBoost model demonstrated superior performance with 88.01% accuracy and a macro F1 score of 0.8803, significantly reducing the False Negative Rate compared to conventional methods.
