The principle of chaos encryption consists of adding a chaotic signal to the message to be transmitted. the transmitter sends to a receiver this chaotic signal where the message is drowned. Knowing the characteristics of the initial chaotic signal lets the receiver know how to extract the message from the received signal. in this paper, we propose a new chaos-based video encryption method and study its performance. the approach of Chaos-based video encryption is implemented in Matlab to encrypt AVI format videos. Choosing an algorithm based on chaos allows us to improve the time/robustness ratio by making the best use of chaotic sequences. the results of tests and evaluations show the performances of our systems. Among these results, we obtained PSNR values up to 8.14, NPCR values around 99.99%, and entropy values up to 7.99.
