| Summary: | The present paper explains the development of an innovative cryptographic system designed to encrypt color images at the pixel level. This technique relies on a significant enhancement of the conventional Vigenere method, incorporating the implementation of two large substitution tables generated from the widely used chaotic maps in cryptography. The system integrates new confusion/diffusion functions, governed by binary decision vectors of pseudorandom values. Simulations conducted on an arbitrary selection of images from a database demonstrate that our system can withstand all known attacks. |
