Condition: Sehr gut. Zustand: Sehr gut | Seiten: 418 | Sprache: Englisch | Produktart: Bücher | Presenting encryption algorithms with diverse characteristics, Image Encryption: A Communication Perspective examines image encryption algorithms for the purpose of 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 approaches. It explores number theory-based encryption algorithms such as the Data Encryption Standard, the Advanced Encryption Standard, and the RC6 algorithms. It not only details the strength of various encryption algorithms, but also describes their ability to work within the limitations of wireless communication systems.Since some ciphers were not designed for image encryption, the book explains how to modify these ciphers to work for image encryption. It also provides instruction on how to search for other approaches suitable for this task. To make this work comprehensive, the authors explore communication concepts concentrating on the orthogonal frequency division multiplexing (OFDM) system and present a simplified model for the OFDM communication system with its different implementations.Complete with simulation experiments and MATLAB® codes for most of the simulation experiments, this book will help you gain the understanding required to select the encryption method that best fulfills your application requirements.…

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - This work is an investigation and study of the mechanism of internal discharges in micro cavities in solid dielectrics with application to power cables. The magnitude, repetition rate and energy, in micro cavities in solid dielectric samples and electrical cables were studied. The field distribution in these cavities was simulated, modeled and calculated for certain applied voltage. Alternating high voltage at power frequency at room temperature was applied to different materials.The cavity shape, cylindrical or spherical, and its dimensions were changed. The size of the cavity was much smaller than the sample thickness. The cavities location and w.r.t electrodes were changed. The study was done on samples of low density polyethylene (LDPE), polyvinylchloride (P.V.C) and ethylene polypropylene rubber (E.P.R) because of their important industrial applications.…

Buch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Investigating image encryption approaches, this book examines image encryption algorithms for the purpose of wireless communication of images in secure form. It considers two directions for image encryption: permutation-based encryption and diffusion-based encryption. Covering the range of image encryption principles and techniques, it presents hybrid encryption algorithms to enhance the characteristics of traditional algorithms. It explores number theory-based encryption algorithms, details the strength of different encryption algorithms, and describes their ability to work within the limitations of wireless communication systems. …
