Security Problem

As is known to all, data transmission in wireless networks is easy to intercept because of the openness of wireless signals. In order to deal with this security problem, this paper presents a secure communication method based on driving-response synchronization and TCP protocol. The video signal is encrypted and decrypted by a chaotic sequence and transmitted through WIFI network in real time. Furthermore, the system configuration and design procedures are described in detail. Experimental results show that our approach is feasible for video secure communication.

AbstractIn this paper, an adversarial encryption algorithm based on generating chaotic sequence by GAN is proposed. Starting from the poor leakage resistance of the basic adversarial encryption communication model based on GAN, the network structure was improved. Secondly, this paper used the generated adversarial network to generate chaotic-like sequences as the key K and entered the improved adversarial encryption model. The addition of the chaotic model further improved the security of the key. In the subsequent training process, the encryption and decryption party and the attacker confront each other and optimize, and then obtain a more secure encryption model. Finally, this paper analyzes the security of the proposed encryption scheme through the key and overall model security. After subsequent experimental tests, this encryption method can eliminate the chaotic periodicity to a certain extent and the model’s anti-attack ability has also been greatly improved. After leaking part of the key to the attacker, the secure communication can still be maintained.

Background/Objective: The Coronavirus Covid-19 has affected almost all the countries and millions of people got infected and more deaths have been reported everywhere. The uncertainty and fear created by the pandemic can be used by hackers to steal the data from both private and public systems. Hence, there is an urgent need to improve the security of the systems. This can be done only by building a strong cryptosystem. So many researchers started embedding different topics of mathematics like algebra, number theory, and so on in cryptography to keep the system, safe and secure. In this study, a cryptosystem using graph theory has been attempted, to strengthen the security of the system. Method: A new graph is constructed from the given graph, known as a double vertex graph. The edge labeling of this double vertex graph is used in encryption and decryption. Findings: A new cryptosystem using the amalgamation of the path, its double vertex graph and edge labeling has been proposed. From the double vertex graph of a path, we have given a method to find the original path. To hack such an encrypted key, the knowledge of graph theory is important, which makes the system stronger. Applications:The one-word encryption method will be useful in every security system that needs a password for secure communication or storage or authentication.

Encryption And Decryption

In this paper two methods are used, namely the vigenere cipher method and the RSA method. The vigenere cipher method is an example of a symmetric algorithm, while RSA is an example of an asymmetric algorithm. The combination of these two methods is called hybrid cryptography which has the advantage in terms of speed during the encryption process. Each process, which is encryption and decryption, is carried out twice, so that security can be ensured. In the process of forming the key used the RSA method. In the encryption process using public keys that have been generated before when the key is formed. This public key is used in sending data to the recipient of a secret message where this key is used for the data encryption process. The Secret key is kept and will be used during the decryption process. There is a system architecture that describes how clients and servers communicate with each other over the internet using the TCP protocol where the client here is an IoT device and the server is a server.

Chaos is characterized by aperiodic, wideband, random-like, and ergodicity. Chaotic secure communication has become one of the hot topics in nonlinear dynamics since the early 1990s exploiting the technique of chaos synchronization. As distinguished by the type of information being carried, chaos-based communication systems can be categorized into analogy and digital, including four popular techniques such as Chaos Masking, Chaos Shift Keying, Chaos Modulation, and Chaos Spreading Spectrum. In this chapter, the principles of these schemes and their modifications are analyzed by theoretical analysis as well as dynamic simulation. In addition, chaos-based cryptography is a new approach to encrypt information. After analyzing the performances of chaotic sequence and designing an effective chaotic sequence generator, the authors briefly presented the principle of two classes of chaotic encryption schemes, chaotic sequence encryption and chaotic data stream encryption.
