Secure Message Transmission: Integrating AES Encryption and LSB Substitution Steganography in a Django-based System

Abstract

Abstract: This study introduces an innovative strategy for ensuring secure message transmission by merging AES encryption with steganography. The proposed technique entails the development of a user-friendly website using Django, facilitating the secure input of messages. The input text is then subjected to encryption using the well-established AES algorithm, recognized for its robust cryptographic capabilities. Subsequently, the encrypted message becomes concealed within an image through the utilization of LSB substitution, a prevalent steganographic method. The paper thoroughly explores the methodology, experimental configuration, and outcomes, effectively showcasing the efficacy of this amalgamated approach. Ultimately, this solution offers a pragmatic remedy for accomplishing covert and secure communication across diverse applications.
