HE-LoRA:- Privacy-Preserving Network Intrusion Detection via Homomorphic Encryption LoRA Fine-Tuning of BERT

Submitted by Katie Dey on

ABSTRACT

With the advancement of large language models, intelligent data analysis has been transformed through context-aware reasoning across diverse domains. In cybersecurity, these capabilities enable automated intrusion detection and anomaly classification from massive network traffic logs. However, fine-tuning language models on raw network data expose critical privacy risks, as logs may contain sensitive information such as IP addresses, payload signatures, and internal communication parameters.
