Features •Presents permutation- as well as diffusion-based encryption algorithms and compares between them •Presents encryption quality metrics •Presents hybrid encryption algorithms to enhance diffusion as well as permutation properties •Develops chaotic encryption approaches with different modes of operations •Introduces the OFDM system model in a simplified form concentration on its limitations •Studies the effect of OFDM limitations on encrypted image communication •Includes MATLAB® codes for most of the simulation experiments in the book Summary Presenting encryption algorithms with diverse characteristics, Image Encryption: A Communication Perspective examines image encryption algorithms for secure wireless communication. It considers two directions for image encryption: permutation-based approaches and substitution-based approaches. Covering the spectrum of image encryption principles and techniques, the book compares image encryption with permutation- and diffusion-based appro
