Abstract

In this paper, a novel method for fast protection of AVS video coding standard along with 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 using 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 affecting the coding efficiency of AVS by keeping the bitrate unchanged, generating completely compliant bitstream and utilizing 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.
