Abstract	Wireless video security becomes an important challenge for commercial applications. Two efficient encryption algorithms for video system, signed integer exponential-Golomb coded (SE) encryption algorithm and context-adaptive variable length coding (CAVLC) encryption algorithm are proposed during the process of the entropy coding. In order to maintain the format compliance, the signs of motion vector difference (MVD), delta quantity parameter (QP) in SE are confused, as well as the levels of nonzero transform coefficients in CAVLC are encrypted by stream cipher. Experimental results demonstrate that the proposed algorithms that encrypt much less important data can achieve high security and low complexity, while still maintain compliance to the compression format. The proposed algorithms are especially suitable for wireless multimedia application.
