We publish the datasets of web traffic traces produced for the closed-world evaluations on non-defended, WTF-PAD and Walkie-Talkie datasets. However, due to the limitation on the size of uploaded files set by Github, we upload our dataset to google drive repository instead.
The dataset can be downloaded from this link
- We serialized the dataset to the pickle file.
- The researcher can simply use the cPickle python's library to load the dataset
- In each sub-folder, it contains 6 different files
X_<type of data>_<type of evaluation>.pkl : Packet's directions sequence
y_<type of data>_<type of evaluation>.pkl : Corresponding website's classes sequece
<type of data> --Three different data sets used for training, validation, and testing
<type_of_evaluation> --Three different evaluations:
NoDef: Tor's trafic traces without defense
WTFPAD: Tor's trafic traces with WTF-PAD defense
WalkieTalkie: WTFPAD: Tor's trafic traces with Walkie-Talkie defense
In all datasets, we use the same data structure as following:
X_<type of data>_<type of evaluation>.pkl --Array of network traffic sequences.
The dimension of X's dataset is [n x 5000] in which
n -- Total number of network traffic sequences instances
5000 -- Fixed length of each network traffic sequence instance.
y_<type of data>_<type of evaluation>.pkl --Array of the websites' labels
The dimension of y's dataset is [n] in which
n --Total number of network traffic sequences instances
E.g.
X_<type of data>_<type of evaluation>.pkl = [[+1,-1, ..., -1], ... ,[+1, +1, ..., -1]]
y_<type of data>_<type of evaluation>.pkl = [45, ... , 12]
In this case:
- the 1st packet sequence [+1,-1, ..., -1] belongs to website number 45
- the last packet sequence [+1, +1, ..., -1] belongs to website number 12
Before training and evaluating DF model please place the downloaded datasets into
dataset/ClosedWorld/ for close world
dataset/OpenWorld/ for open world
First of all, you will need to download the corresponding dataset and place it in:
dataset/ClosedWorld/NoDef/ directory for non-defended

- The dataset format and description are the same as closed-world dataset
- The dataset can be downloaded from this link
First of all, you will need to download the corresponding dataset and place it in:
dataset/OpenWorld/NoDef/ directory for non-defended
dataset/OpenWorld/WTFPAD/ directory for WTF-PAD
dataset/OpenWorld/WalkieTalkie/ directory for Walkie-Talkie
The source codes contain two part:
- The model includes both monitored and unmonitored websites used to train the DF model with respect to each evaluation.
- To train the model
python src/OpenWorld_DF_<type of evaluation>_Training.py
- The output of this part is the trained DF model that will be used in the next part.
- After finishing training the model, the trained DF model will be automatically saved at
../saved_trained_models/OpenWorld_<type of evaluation>.h5
- The performance of the attack in open-world scenario is evaluated by running
python src/OpenWorld_DF_<type of evaluation>_Evaluation.py
- The output of the evaluation will be automatically saved in the
../results/OpenWorld_<type of evaluation>.csv
- In each row of the csv file consists of the related performance metrics with respect to different thresholds including
True Positive (TP) False Positive (FP) True Negative (TN) False Negative)
True Positive Rate (TPR) False Positive Rate (FPR)
Precision and Recall
- The researcher can use this performance metric to plot ROC or Precision&Recall curves.
- Note that our research work mainly focus on the use of precision and recall as the main performance metric.
