VIDEO ENCRYPTION BASED ON CHAOTIC SYSTEM AND STREAM CIPHER

Abstract

The huge development and use of digital multimedia (video, image) over computer networks has led toincrease the need for securing of these digital data. Video encryption is widely used as a method for providing securityfor digital video. In this paper video encryption method is developed using chaotic system for key generator andstream cipher, it uses chaotic map as one-time key generator which produce key used for encryption process. Chaoticsystems have been successfully used for multimedia encryption. Chaotic cryptography have good characteristic suchas pseudo-randomness, and sensitivity to initial conditions. Video encryption method have successfully designed andimplemented, the tests and analysis results have showed the succeed of the encryption method in term of speedand security.
