Dora: Online Scheduling of Dual-Model Inference and Retraining for Multi-View Edge Systems

Published in IEEE Transactions on Mobile Computing (Early Access), 2026

Dora coordinates inference and retraining for feature extraction and fusion models on resource-constrained edge servers. Its online scheduler adapts to data drift and balances response time against sustained prediction quality.

SCEP-TI: A side-channel attack on encrypted proxy video streams for video title identification

Published in Computer Networks, 2025

This work presents SCEP-TI, a novel method that leverages side-channel features in encrypted proxy video streams to accurately identify video titles. The approach demonstrates that even encrypted traffic can leak sensitive information through traffic patterns, posing new privacy and security risks.

Peering Through the Veil: A Segment-Based Approach for VPN Encapsulated Video Title Identification

Published in TrustCom2024, 2024

We propose a segment-based method for identifying video titles from VPN-encapsulated traffic, achieving accurate recognition despite encryption and tunneling obfuscation.
