Secure communication framework using lattice-based encryption and image steganography

Ensuring secure communication in modern digital networks is crucial to safeguarding sensitive information. This paper presents a novel framework that combines lattice-based encryption with image steganography to enhance data security and confidentiality. Lattice-based encryption offers strong resistance against quantum computing attacks, making it a robust choice for cryptographic security. Meanwhile, image steganography effectively conceals encrypted data within multimedia content, adding a layer of protection. The proposed framework leverages mathematical principles to optimize encryption strength while minimizing distortion in the steganographic process.
