An audio scrambling method based on combination strategy

In this paper, two audio scrambling algorithms, which are efficient and can be used to scramble audio sequence independently, are presented first. Then, a new method which combines the two algorithms together using one more parameter is proposed. Compared with the former two methods, the new method has stronger anti-decryption capability. Experimental results show that this method has the advantage of good scrambling effect, strong anti-attack capability and strong anti-decryption capability.
