Dynamic Shuffling for Speed Image Encryption

Encryption security and encryption speed are two important aspects of image encryption algorithms. Due to their increasingly large size, video images present a great challenge to currently available cryptographic algorithms; the processes of encryption and decryption of images are so computationally intensive that they introduce delays beyond acceptable real-time application limits. [1] In this paper we introduce a new algorithm that uses Dynamic Total Shuffling as both encryption keys and the control stream to verify which key will be used for each block. The goal is to provide a highly secure encryption algorithm with a wide space for encryption speed. General Terms Pattern Recognition, Security, Algorithms, Chaotic
