Review of Enhancing Secure Communication: Unified Study of Cryptographic and Steganographic Techniques in Digital Communication template

In a time of rising cyber threats and widespread digital communication, protecting sensitive information is crucial. This paper offers a detailed survey and analysis of current methods in secure communication, focusing on the relationship between cryptographic systems and steganographic techniques. We base our work on foundational mathematics, especially commutative algebra, and use modern technologies like Generative Adversarial Networks (GANs), zero-knowledge proofs, and quantum-resistant algorithms. We present a layered approach to information security. We discuss how combining classical and modern cryptography with improved steganographic embedding and signal processing techniques highlights the need for hybrid and adaptable models to protect communication. This study aims to be a reference point for future research and development in secure digital systems.
