  Securing multimedia data has become of utmost importance especially in the
applications related to military purposes. With the rise in development in
computer and internet technology, multimedia data has become the most
convenient method for military training. An innovative encryption algorithm for
videos compressed using H.264 was proposed to safely exchange highly
confidential videos. To maintain a balance between security and computational
time, the proposed algorithm shuffles the video frames along with the audio,
and then AES is used to selectively encrypt the sensitive video codewords.
Using this approach unauthorized viewing of the video file can be prevented and
hence this algorithm provides a high level of security. A comparative study of
the proposed algorithm with other existing algorithms has been put forward in
this paper to prove the effectiveness of the proposed algorithm.
