Abstract	Video encryption is an important field. It has been recently rapidly used in many multimedia systems. The proposed method is focusing on H.264/AVC [1] [2] video coding standard. Several encryption algorithms are based on intra frame/slice had been utilized. The drawbacks of previously used algorithms is that they are vulnerable to known plaintext attack, the increase of stream size, they can't handle real-time processing and they face bandwidth limitations of bit rate [3]. The proposed algorithm is to secure a video during encoding process. The proposed method uses Selective Encryption(SE) [4] to encrypt a CAVLC (Context Adaptive Variable Length Code) stage in order to minimize the amount of bits on compressed file. The security is based on the security of stream cipher. The most important factor here is the compact ratio, Bit rate and Frame rate.
