These include improving the security and efficiency of these cryptosystems, as well as exploring new applications and integrating them with other cryptographic techniques. In conclusion, the scientific paper provides a comprehensive overview of cryptosystems based on finite automata, their classification, and their various applications in the field of cryptography. In this paper [24] paper by [PERSON] and [PERSON] present a novel authenticated encryption scheme based on the finite automata cryptosystem. The authors demonstrate that their method offers competitive performance and security properties, making it a promising candidate for real-world applications in the field of cryptography. In recent years, the field of nonlinear dynamics has seen significant advancements, particularly in the study of deterministic chaotic systems. This paper [25], by [PERSON], [PERSON], [PERSON], and [PERSON], explores the concept of deterministic chaos in the context of finite-state automata, a fundamental concept in computer science and automata theory. The authors present a novel approach to modeling and analyzing deterministic chaos in finite-state automata, which has potential applications in various fields such as secure communication, cryptography, and control systems. The paper concludes by discussingthe potential applications of deterministic chaotic finite-state automata in various fields, such as secure communication, cryptography, and control systems. The authors emphasize the need for further research to explore the potential of these systems and their practical implementation. In recent years, the use of unmanned aerial vehicles (UAVs) has become increasingly prevalent in various industries, including military, agriculture, and environmental monitoring. The exchange of data between UAVs and ground stations is crucial for the efficient functioning of these systems. However, ensuring the security of these data is of utmost importance, as unauthorized access can lead to significant consequences. To address this concern, a new image encryption algorithm based on a DNA state machine has been proposed for UAV data encryption. In this scientific paper [26] by [PERSON], [PERSON], and [PERSON], the authors present a novel image encryption algorithm that utilizes the principles of DNA state machines to provide robust security for UAV data transmission. The primary objective of this algorithm is to enhance the security of UAV data while maintaining the efficiency of the overall communication process. In conclusion, the new image encryption algorithm based on DNA state machines presents a promising solution for securing UAV data transmission. The algorithm offers high levels of security, efficiency, and visual quality, making it an attractive option for use in various UAV-based applications. The authors of the paper have demonstrated the effectiveness of their algorithm through a comprehensive evaluation and comparison with other encryption techniques.
