FlowCLIP: Contrastive Pretraining Using Domain Names for Encrypted Traffic Classification (opens in new tab)

Network traffic classification enables website fingerprinting, intrusion detection, and Quality of Service management. However, developing methods that capture stable and generalizable traffic patterns under realistic deployment conditions remains challenging. We introduce FlowCLIP, a contrastive pretraining framework for domain name prediction from encrypted traffic using only side-channel features: packet inter-arrival times, packet sizes, and...
