This article presents a selective encryption (SE) chaotic video stream cipher for the scalable extended high-efficiency video coding (SHVC) bitstream. The proposed SHVC SE uses a logistic map (LM) for enciphering the motion vector difference (MVD), discrete cosine transform (DCT) coefficients and delta quantization parameter (dQP) sign bits. The SHVC SE chaotic video stream cipher is proposed to secure the most sensitive bits of the SHVC while keeping the video format compliance feature. Also, this paper presents a performance analysis for the proposed SHVC SE and the AES in CFB operation mode. Experimental results illustrate the main feature of using the LM in the proposed SHVC SE, which is lower latency encoding time for the SHVC SE chaotic video stream cipher than using the AES in CFB operation mode. Security investigations are performed on the proposed SHVC SE for ensuring the robustness of the ciphered SHVC digital video against unauthorized attacks.

用于高效视频编码可扩展扩展的低延迟选择性加密方案

本文提出了一种用于可扩展扩展高效视频编码 (SHVC) 比特流的选择性加密 (SE) 混沌视频流密码。所提出的 SHVC SE 使用逻辑图 (LM) 来加密运动矢量差 (MVD)、离散余弦变换 (DCT) 系数和增量量化参数 (dQP) 符号位。提出了 SHVC SE 混沌视频流密码以保护 SHVC 的最敏感位，同时保持视频格式合规性特征。此外，本文还对所提出的 SHVC SE 和 CFB 操作模式下的 AES 进行了性能分析。实验结果说明了在所提出的 SHVC SE 中使用 LM 的主要特征，即与在 CFB 操作模式下使用 AES 相比，SHVC SE 混沌视频流密码的延迟编码时间更低。
