Abstract

The proposed method for implementing cryptographic traffic detector systems and evasive tools in this article is a method based on deep learning, which due to the importance of optimal and automatic extraction of features from the input data set, an automatic encoder network has been used in the feature extraction phase. Then, the output of the middle hidden layer of this network is applied to a deep convolutional neural network. Deep convolutional neural networks can play an effective role in improving the performance of the system by taking into account the spatial connections between features. Finally, the output of deep convolutional neural network is also applied to two fully connected layers in order to perform the classification process. So that the number of neurons in the second fully connected layer will be equal to the expected number of layers of the system. In the first part of this article, the specifications of the proposed systems for the implementation of cryptographic traffic detectors and evasion tools will be mentioned in terms of operational architecture and features. Then, the characteristics of the networks used in the implementation of the system, and the method of their integration to form the final identifier system are briefly stated. After that, the training stage of the system and its implementation method will be introduced and at the end, how to adjust the parameters of the model and the mechanisms used to improve the overall performance of the system and the results of its performance evaluation will be presented.

Abstract

The development of the country's infrastructure as an independent, safe and stable infrastructure is one of the strategic priorities of the country, the realization of which, in addition to the technological requirements in the field of information and communication technology, laying the foundation for the establishment, development and supply of various services and content of the country's cyber space, requires the provision of secure communications. And the vital infrastructure of the country is also stable.
Based on the conceptual model contained in the resolution of the 66th meeting of the Supreme Council of Cyberspace, the communication and information infrastructure of the country consists of a series of main modules, whose risk analysis is in line with the reversibility in accidents, protection against threats, monitoring and intelligent response from the basic needs of communication access. It is safe and secure. Due to the space limitations of this article, the author intends to explain how to achieve multi-sample risk analysis from these basic modules and then based on the results, how to exploit the emerging knowledge in the form of a diagram to identify the type of threat and its source and extract Explain the mentioned preventive requirements.
