The prevalence of internet, as well as low-cost mobile computing devices, makes video the preferred option for information archival and transmission. Also, the geometric growth in the generation and use of digital videos is massive and challenging to determine. Meanwhile, this growth has come with security and privacy issues such as unauthorized access, piracy, hacking and other digital attack every year. Restricting unauthorized access measure can be adopted to protect multimedia information, but does not guarantee the physical security of information. Cryptography which is a better and more secure approach is therefore required. Thus, this paper presents performance evaluation of Enhanced Novel Selective Video Encryption Algorithm, an AES-based video encryption algorithm. Properties of I frame are used randomly to generate the encryption key and a jump factor is used to determine which of the remaining P and B frame is selected for encryption. The results show that the more frames selected for encryption/decryption, the higher the encryption/decryption time and the higher the encrypted video size. Also, the PSNR value of this algorithm is around 40dB which indicates that the quality of the decrypted video is as high as that of the original video. The performance of this algorithm does not diminish with increase in size of video and number of frames. Hence, this algorithm is scalable, fast and highly secure for video encryption.

“…And these encryption schemes are different in terms of security, computational complexity and encryption/decryption speed due to different scenarios. There are two kinds of common video encryption technologies (Malladar and Kunte, 2016), one is full encryption (Negi, 2013;Iyer et al, 2017;Giradkar and Bhattacharya, 2015), the other is selective encryption (Khan, 2017;Dufaux and Ebrahimi, 2008;Saleh et al, 2015;Hamidouche et al, 2017;Hole and Kolhekar, 2017). Several encryption schemes have been proposed in the literature.…”

In recent years, researchers have proposed a number of encryption algorithms and encryption schemes to protect the privacy of individuals or businesses. However, these encryption algorithms and encryption schemes are difficult to achieve a certain balance in term of encryption efficiency and security. In order to achieve this goal as much as possible, we propose a hybrid encryption technique, which makes the best use of two encryption techniques to achieve higher security and faster speed of encryption algorithm. We introduce two techniques in this hybrid encryption scheme. The first is scrambling and the second is encryption. We evaluated the performance of encrypted video by comparing the PSNR and SSIM values of the scrambled video and the encrypted video. Experimental results show that the proposed scheme has high encryption efficiency and good security.
