Hybrid Encryption Algorithms Over Wireless Communication Channels
“Hybrid Encryption Algorithms Over Wireless Communication Channels” by Mai Helmy Shaheen, published by CRC Press in 2021, explores innovative hybrid encryption algorithms tailored for secure wireless communications. This edition, comprising 258 pages, delves into the intricacies of encrypted image and video data, focusing on two distinct families of encryption schemes: permutation-based and diffusion-based. The book aims to guide readers in selecting the most appropriate scheme for transmitting encrypted media, utilizing various encryption and decryption quality metrics.
Readers will find a comprehensive examination of number-theory based encryption algorithms, including chaotic theory, the Advanced Encryption Standard (AES), and RC6, applied in a pre-processing step to achieve necessary permutations and diffusions. The author also discusses the importance of effective encryption and modulation schemes in modern communication systems, adopting Orthogonal Frequency Division Multiplexing (OFDM) for wideband communications. Additionally, the book addresses the sensitivity of encrypted data to wireless channel impairments and the impact of channel equalization on the quality of received images and videos. Complete simulation experiments with MATLAB® codes are included to enhance understanding and application of the discussed methods.
Official synopsis Publisher
This book presents novel hybrid encryption algorithms that possess many different characteristics. In particular, “Hybrid Encryption Algorithms over Wireless Communication Channels”, examines encrypted image and video data for the purpose of secure wireless communications. A study of two different families of encryption schemes are introduced: namely, permutation-based and diffusion-based schemes. The objective of the book is to help the reader selecting the best suited scheme for the transmission of encrypted images and videos over wireless communications channels, with the aid of encryption and decryption quality metrics. This is achieved by applying number-theory based encryption algorithms, such as chaotic theory with different modes of operations, the Advanced Encryption Standard (AES), and the RC6 in a pre-processing step in order to achieve the required permutation and diffusion. The Rubik’s cube is used afterwards in order to maximize the number of permutations.
Transmission of images and videos is vital in today’s communications systems. Hence, an effective encryption and modulation schemes are a must. The author adopts Orthogonal Frequency Division Multiplexing (OFDM), as the multicarrier transmission choice for wideband communications. For completeness, the author addresses the sensitivity of the encrypted data to the wireless channel impairments, and the effect of channel equalization on the received images and videos quality.
Complete simulation experiments with MATLAB® codes are included. The book will help the reader obtain the required understanding for selecting the suitable encryption method that best fulfills the application requirements.
