Book Description

Transmission of images and videos is a vital part of today’s communication systems. As such, an optimum encryption scheme and an optimum modulation method is important. Orthogonal frequency division multiplexing (OFDM) is an attractive multicarrier transmission technique for wideband communications, because it effectively transforms the frequency selective fading channel into a flat fading channel. Hence, OFDM provides greater immunity to multipath fading and impulsive noise, and eliminates the need for complicated equalizers. However, OFDM communication systems suffer from fading effects, high sensitivity to carrier frequency offsets and phase noise.

In this book, we present a study for two different families of encryption schemes; permutation based schemes and diffusion based schemes. The objective of this study is to select the better suited scheme for encrypted image transmission over communication systems. Encryption and decryption quality metrics are used in the comparisonpresented. Two modifications are presented in this thesis in the permutation and diffusion algorithms to enhance their properties. In the proposed hybrid encryption framework, we need to achieve both diffusion and permutation in the encrypted 3D images. To achieve this, the author uses chaotic or RC6 or AES technique in a pre-processing step to achieve the permutation and diffusion. The Rubik’s cube is used afterwards to achieve a greater number of permutations. The book then reviews its sensitivity to the wireless channel impairments, and the effect of channel equalization on the received 3D images quality.
