dc.description.abstract In this paper we propose a real-time selective video encryption solution in the scalable extension of High Efficiency Video Coding (HEVC) standard, referred to as SHVC. The proposed scheme encrypts a set of sensitive SHVC parameters with a minimum delay and complexity overheads. The encryption process is performed at the CABAC binstring level and fulfils both constant bitrate and format compliant video encryption requirements. In addition, it preserves all SHVC functionalities, including bitstream extraction for mid-network adaptation and error resilience. We compare the performance of three selective SHVC encryption schemes: the first scheme encrypts only the lowest SHVC layer, the second encrypts all layers and the last scheme encrypts only the highest layer. The performance of the proposed schemes is assessed over different video encryption criteria, at different scalability configurations and various High Definition (HD) video sequences. Experimental results showed that encrypt only the lowest layer or all layers enables a high security level, while encrypting only the highest layer leads to a perceptual encryption solution, by slightly decreasing the highest layer quality. Moreover, the processing complexity of the proposed solution is assessed in the context of a real-time SHVC decoder. The complexity overhead remains low and does not exceed 6% of the real-time decoding of SHVC video sequences. en_US
