Abstract: Chaos-based encryption, when combined with ElGamal cryptographic frameworks, offers a robust approach to securing communication in distributed systems. This project explores a hybrid cryptosystem that leverages the sensitivity to initial conditions in chaotic functions and the discrete logarithm problem underlying ElGamal encryption. By integrating chaotic key generation techniques, such as logistic maps and Gray code transformations, with ElGamal's asymmetric encryption, the system ensures enhanced data confidentiality, integrity, and resilience to cryptographic attacks. The experimental evaluation demonstrates that the proposed hybrid model achieves significant improvements in security, computational efficiency, and resistance to cryptanalysis, including side-channel and brute force attacks. Additionally, the system is designed to facilitate efficient key management, while ensuring adaptability for lightweight devices and real-time secure communication protocols. This contribution highlights the potential of chaos-based-ElGamal hybrid cryptography as a secure and scalable solution for modern communication networks.
