Download or read book Encryption and Decryption Algorithms for Plain Text and Images using Fractional Calculus written by Rafael Martínez-Guerra and published by Springer Nature. This book was released on 2023-01-17 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers an alternative for encrypting and decrypting messages using objects called integer and fractional-order estimators or observers, by means of security codes. The authors first establish the class of observers capable of carrying out this work. Then, the type of observers to treat either the integer or fractional order type and their main characteristics is mentioned. The book also presents an essential property of some systems such as Liouville, which is vital for the encryption and decryption of messages in integer and fractional order nonlinear systems by using the synchronization property of chaotic systems. Finally, it addresses some logistic maps such as Mandelbrot sets including Julia and fractal sets, taking advantage of their characteristics to encrypt or recover messages.
