The research deals with implementation of a new algorithm to encrypt multimedia  files this method called random scrambling, to increase the security of the transmitted files, a secret key is used to prevent unauthorized persons from extracting these files. The encryption applied on image, sound, and video files, Matlab is used to implement the algorithm due to the facilities it provides for dealing with multimedia files as well as GUI. Finally, experimental results demonstrate the efficiency of the algorithm in the encryption of Multimedia files.
