SECURE VIDEO EXCHANGE SYSTEM BASED ON STREAM CIPHER AND LORENZ SYSTEM

Abstract: The huge development in communication, multimedia and networks technologies lead to huge increase in using and transmitting of digital video, with that development the need for securing of these digital data is increased. Video encryption is vastly used to provide security for digital video. In this paper a system for secure video exchange is suggested, which consist of proposed video encryption method based on stream cipher and chaotic system as a key generator. Chaotic systems have been used successfully with cryptography. Chaotic system has characteristic make it suitable to be used in encryption such as pseudo-randomness, and sensitivity to initial conditions. Secure Video exchange system with proposed video encryption method have been successfully designed and implemented, the analysis results and tests on the system demonstrated that the encryption method has good results in term of speed and security.
