摘要: security and encryption speed are two important aspects of image algorithms. Due to their increasingly large size, video images present a great challenge currently available cryptographic algorithms; the processes decryption so computationally intensive that they introduce delays beyond acceptable real-time application limits. (1) In this paper we new algorithm uses dynamic square matrices as both keys control stream verify which key will be used for each block. The study case showed in works on GF(7) sizes varying from 3X3 12X12 goal is provide highly secure with wide space speed.
