Abstract
The security of multimedia content and its applications have become a a very important task in digital communication technology. The extensive use of multimedia content over wireless networks makes the network applications exposed to different types of attacks. Cryptography is one of the main technologies that provide security and confidentiality to prevent unauthorised data access. A suitable design of an encryption system must be chosen to fully secure and maintain the privacy of data. On the other hand, the large size of data will be the prominent issue. In order to maintain a better performance of Internet-of-Things (IoT) applications, an appropriate compression-encryption scheme has to be used to ensure security and high speed without increasing the cryptosystem complexity in order to achieve a large communication capacity. Therefore, this paper presents a hybrid scheme of H.264/MVC compression and encryption process based on Latin Square Cipher (LSC) using symmetric keys. The Latin Square Whitening and Latin Square Substitution and Permutation operations are included in the encryption algorithm. The simulation results and analysis on different RGB video frames using MATLAB show that the proposed scheme achieves high protection, integrity, and security performance for different transmitted video frames. In addition, high robustness against different network attacks is achieved compared to the state-of-the-art algorithms.
