Design and Implementation of Format-compliant Video Encryption Algorithm
Luo Da-jiang · Jisuanji gongcheng · 2010
Format-compliant video encryption algorithms have their own merits and defects on safety,operability and decoding time-consuming.Aiming at the situation,this paper proposes a novel format-compliant video encryption algorithm which is convenient,secure,fast and has no effect on the compression ratio.Videos are encrypted by permutation through changing the value of the vertical position for macro-blocks.Simulation results on two standard video sequences show that compared with the original one,the new algorithm is more effective.
