Summary:
To strengthen the protection of privacy information in videos, a selective encryption scheme for HEVC is proposed in this paper. In this scheme, the pseudo random binary sequence generator is first constructed based on Rossler chaotic system. After that, the generated key stream is used to encrypt the motion information and residual coefficients of HEVC. Especially for the encryption of residual coefficients, the improved scrambling effect is achieved by encrypted DC coefficients. Experimental results and analysis show that the proposed scheme can produce a good encryption effect, and keep the encrypted stream format-compliant
