The paper outlines an approach that combines cryptography and steganography to enhance digital security. It explores various cryptographic algorithms, including the Diffie-Hellman key exchange protocol, the RSA algorithm, and the Elgamal algorithm, and compares the performance of RSA and Elgamal in terms of encryption and decryption speed.
The paper also delves into steganographic techniques, focusing on the Least Significant Bit (LSB) method and GAN-based steganography. It analyzes the effectiveness of these techniques using metrics like Mean Squared Error (MSE) and Peak Signal-to-Noise Ratio (PSNR).
Furthermore, the paper presents a hybrid approach that combines cryptography and steganography, utilizing a concatenated GAN architecture. This approach encrypts the message using the RSA algorithm and then embeds the encrypted message into an image using GAN-based steganography, providing a dual layer of security.
The experimental results demonstrate the trade-offs between image quality and security across the different steganographic methods. The LSB algorithm is shown to be best suited for applications where image quality is a priority, while the GAN-based and concatenated methods are more suitable for scenarios that demand high security for the embedded data, even at the cost of image quality.
The paper concludes by highlighting the potential future directions for research in this field, including exploring other network architectures, expanding the types of secret information that can be hidden, optimizing efficiency, and enhancing security against various attacks.
