摘要:

TOR(The Onion Router)网络是一种被广泛使用的开源匿名通信工具,TOR的滥用使得监控网络犯罪的扩散变得困难,如访问犯罪网站。大多数现有的TOR网络去匿名化方法严重依赖于手动提取的特征,导致耗时且性能差。针对上述不足,提出一种基于分类算法的神经表示学习方法来识别网站指纹。基于卷积神经网络(CNN),通过伸缩和因果卷积,构建了一种新的网站指纹攻击模型,该模型既能提高CNN的感知域,又能捕捉到输入数据的序列特征。在三个主流公开数据集上的实验表明,该模型对网站指纹分类具有鲁棒性和有效性,与现有方法相比,准确率提高了12.21%。

英文摘要:

TOR (The Onion Router) network is a widely used open source anonymous communication tool, the abuse of TOR makes it difficult to monitor the proliferation of online crimes such as to access criminal websites. Most existing approches for TOR network de-anonymization heavily rely on manually extracted features resulting in time consuming and poor performance. To tackle the shortcomings, this paper proposes a neural representation learning approach to recognize website fingerprint based on classification algorithm. We constructed a new website fingerprinting attack model based on convolutional neural network (CNN) with dilation and causal convolution, which can improve the perception field of CNN as well as capture the sequential characteristic of input data. Experiments on three mainstream public datasets show that the proposed model is robust and effective for the website fingerprint classification and improves the accuracy by 12.21% compared with the state-of-the-art methods.
