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 square matrices as both encryption keys and the control stream to verify which key will be used for each block. The study case showed in this paper works on GF(7) and for encryption key sizes varying from 3X3 to 12X12 The goal is to provide a highly secure encryption algorithm with a wide space for encryption speed.
