## 2 Literature Review  
The 2008 book authored by [PERSON] [15] delves into finite automata and their applications in cryptography, offering a comprehensive exposition of the pivotal role played by finite automata within cryptographic systems. The book discusses the different types of finite automata, their applications in cryptography, and the importance of security and efficiency in cryptographic systems. By exploring these concepts and techniques, the paper offers valuable insights into the use of finite automata in the development and implementation of secure and efficient cryptographic systems. In the scientific paper [16] by [PERSON], [PERSON], and [PERSON], the authors present a detailed analysis of the Secure Sockets Layer (SSL) 3.0 protocol. SSL is a widely used cryptographic protocol that ensures secure communication between a client and a server over the Internet. The authors aim to analyze the potential vulnerabilities and attacks on SSL 3.0 by employing finite-state machine techniques. Their findings underscore the need for continued research and development in the field of cryptography to ensure the security and privacy of Internet communications. In the field of cryptography, ensuring the secure exchange of cryptographic keys is a vital aspect of preventing unauthorized access. In this scientific paper [17], [PERSON], [PERSON], [PERSON], [PERSON], and [PERSON] propose a new cryptographic key exchange protocol that uses message authentication codes (MAC) and finite state machines. The protocol offers strong security guarantees and improved efficiency compared to other existing key exchange protocols. The authors use MAC to ensure the integrity and authenticity of the exchanged messages, while finite state machines are employed to manage the state transitions during the key exchange process. The scientific paper by [PERSON] and [PERSON] [18] explores the relationship between cryptography and learning in the context of boolean formulae and finite automata. This paper investigates the limitations of learning algorithms in the presence of cryptographic techniques and discusses how these limitations can be applied to improve the security of learning systems. The authors begin by providing an overview of the field of cryptography and its applications, with a focus on the role of cryptographic primitives in securing communication and protecting sensitive information. They then introduce the concept of learning algorithms, which are used to identify patterns and structure within datasets and discuss the potential vulnerabilities that these algorithms may exhibit when faced with cryptographic techniques. In recent years, the application of finite automata in cryptography has gained significant attention due to its ability to provide enhanced security and efficiency in various cryptographic algorithms. In this scientific paper [19] by [PERSON], [PERSON], and [PERSON], the authors explore the potential of finite automata in the design and implementation of cryptographic systems. By exploring various cryptographic applications of finite automata, the authors demonstrate that this mathematical model can be a valuable tool in the development of secure and efficient cryptographic algorithms. The scientific paper [20] by [PERSON], [PERSON], and [PERSON] investigates the use of linear finite automata in cryptographic systems. In this paper, the authors present a detailed study of the properties and characteristics of linear finite automata and their potential applications in cryptography. By examining the properties and characteristics of LFAs and analyzing their use in various cryptographic protocols, the authors demonstrate the potential of LFAs as a powerful tool in the field of cryptography. Automata theory offers a powerful mathematical framework for the design and analysis of encryption and decryption algorithms. The cryptosystem presented in this paper [21] demonstrates the practical application of Automata theory in the field of cryptography.
