Description
Summary:This paper presents a chaotic Arnold map (CAM)-based selective encryption (SE) bitstream cipher for the scalable High-Efficiency Video Coding (SHVC). The proposed CAM-based SHVC-SE bitstream cipher employs the CAM for ciphering the coefficients sign bits of Discrete Cosine Transform (DCT), the Motion Vector Difference (MVD) and Sample Adaptive Offset (SAO). The proposed CAM-based SHVC-SE bitstream cipher is designed with the potential of encrypting the SHVC mostly sensitive information bits while preserving the video format compliance characteristic. The performance of the proposed CAM-based SHVC-SE bitstream cipher is compared to with the AES-based SHVC SE in CFB operation mode. The achieved outcomes demonstrates the advantage of employing the CAM in the proposed CAM-based SHVC-SE bitstream cipher that results in decreasing the encoding time for the proposed CAM-based SHVC-SE bitstream cipher compared with the AES-based SHVC SE in in CFB operation mode. Security tests on the proposed CAM-based SHVC-SE bitstream cipher are carried out for testing the robustness of the proposed CAM-based SHVC-SE bitstream cipher against attacks. The results of security tests demonstrated and confirmed the efficiency of the proposed CAM-based SHVC-SE bitstream cipher.
