Enhancing Security of Text Using Affine Cipher and Image Cryptography

In the contemporary digital landscape, the escalating reliance on diverse social media platforms for textual communication necessitates the establishment of secure and trustworthy channels to thwart the threats of theft or hacking. Most of these messages contain highly confidential data, underscoring the critical need for robust security measures, primarily through the deployment of encryption techniques. While existing algorithms predominantly employ text-to-text encryption (TOTET) methods, this paper introduces an innovative hybrid approach that amalgamates TOTET with text-to-image encryption (TOIET), thereby fortifying the privacy of transmitted messages. This novel method undergoes rigorous testing using various parameters, including privacy levels and encryption time, to evaluate its effectiveness. Comparative analyses are conducted against established techniques such as DES, 3DES, and AES. The experimental results conclusively demonstrate the superior privacy capabilities of the proposed scheme in comparison to its predecessors. This advancement in encryption technology not only bolsters the security of confidential messages but also positions itself as a noteworthy improvement over existing methods, marking a pivotal step towards ensuring the integrity of digital communications.
