Query: ET-BERT: A Contextualized Datagram Representation with Pre-training
  Transformers for Encrypted Traffic Classification   Encrypted traffic classification requires discriminative and robust traffic
representation captured from content-invisible and imbalanced traffic data for
accurate classification, which is challenging but indispensable to achieve
network security and network management. The major limitation of existing
solutions is that they highly rely on the deep features, which are overly
dependent on data size and hard to generalize on unseen data. How to leverage
the open-domain unlabeled traffic data to learn representation with strong
generalization ability remains a key challenge. In this paper,we propose a new
traffic representation model called Encrypted Traffic Bidirectional Encoder
Representations from Transformer (ET-BERT), which pre-trains deep
contextualized datagram-level representation from large-scale unlabeled data.
The pre-trained model can be fine-tuned on a small number of task-specific
labeled data and achieves state-of-the-art performance across five encrypted
traffic classification tasks, remarkably pushing the F1 of ISCX-Tor to 99.2%
(4.4% absolute improvement), ISCX-VPN-Service to 98.9% (5.2% absolute
improvement), Cross-Platform (Android) to 92.5% (5.4% absolute improvement),
CSTNET-TLS 1.3 to 97.4% (10.0% absolute improvement). Notably, we provide
explanation of the empirically powerful pre-training model by analyzing the
randomness of ciphers. It gives us insights in understanding the boundary of
classification ability over encrypted traffic. The code is available at:
