This research paper presents an innovative approach to fortify cryptographic systems by integrating Fibonacci polynomials into network security protocols. Leveraging the unique characteristics of polynomials and Fibonacci sequences, our methodology establishes public and private keys, enhancing message transmission security. Initial encryption with polynomials is followed by incorporating Fibonacci polynomials for an added layer of protection. Through this study, we demonstrate how Fibonacci techniques can enhance system security, providing advanced safeguards for network communications. By integrating polynomials and Fibonacci methods, our approach strengthens defense against potential threats, elevating overall system security. This innovative Polynomial-Fibonacci Hybrid Cryptography offers a promising avenue for enhancing data security in contemporary communication systems amidst escalating digital challenges.
