Abstract
A novel Variable Dimension Space Audio Scrambling Algorithm Against MP3 Compression is proposed. The algorithm is implemented in audio position space, which changes the dimension of coordinates and uses arbitrary matrices to scramble audio. The scrambled audio was segmented and a sequence number is embedded in the front of each segment to discriminate different segments. The proposed method can increase the combination of encrypting parameters, which increases the difficulty being attacked; random generated high dimensional transform matrix has no fixed period and has no special restriction on the audio length; a sequence number can be used to determine the each segment audio positions, so the scrambled audio compressed by MP3 can be recovered. Experiments show the proposed algorithm is validity in audio scrambling, low cost in recovering the scrambled audio and still has a wonderful one time scrambling performance. The proposed algorithm is robust in enduring MP3 attacks.
