Applications of multimedia data deal more with security and privacy of video content since they are spreading in cloud computing environments. Encryption methods are limited because even if they can protect video content, they hardly succeed in balancing codec compatibility and security. And when they succeed, they impact video processing speed.

To address this issue, some researchers propose a new video security scheme that balances encryption speed and security.

Their scheme consists in:

• Creating a framework for secure video transmission then applying algorithms within it.
• Reducing security and calculate the time complexity required to break the encryption, then providing security.
• Through comparisons, demonstrating that this scheme has advantages in time efficiency when processing large video files.
