Hybrid Image Encryption for Medical and Defence Applications
摘要
This project proposes a secure image encryption algorithm using Argon2 key generation, confusion using Fibonacci transform and diffusion using logistic map to increase the security of the image. The image is converted into a 16-byte key which is then used for cryptographic purpose. The key-dependent Fibonacci transform scrambles the image by distorting the pixel intensities. The logistic map used for diffusion can change dramatically with just a change in key the decryption process accurately reverses these steps to recover the original image. Simulations show that it securely images transmission and safe image storage through significant strengths, most notably high entropy, low correlation, and differential attack resistance.
