SELECTIVE ENCRYPTION OF C2DVLC OF AVS VIDEO CODING STANDARD FOR I & P FRAMES

In this paper, a novel method for fast protection of AVS video coding standard alongwith compression is presented. Here the problems of compression and selective encryption (SE) have been simultaneously addressed for AVS part-2 Jizhun profile. It is performed in the context-based 2D variable length coding (C2DVLC) module of video codec. SE is performed by us-ing the Advanced Encryption Standard (AES) algorithm with the Cipher Feedback (CFB) mode on a subset of codewords. C2DVLC serves the purpose of encryption step without affect-ing the coding efficiency of AVS by keeping the bitrate un-changed, generating completely compliant bitstream and utiliz-ing negligible computational power. Nine different benchmark video sequences containing different combinations of motion, texture and objects are used for experimental evaluation of the proposed algorithm
