[Other] Built-in-pseudorandom-generators DL : 0: In recent years, a large number of discrete chaotic cryptographic algorithms have been proposed. The chaotic based cryptograms are suitable for large-scale data encryption such as images, videos or audio data. This paper propose a novel higher dimensional chaotic system for audio encryption, in which variables are treated as encryption keys in order to achieve secure transmission of audio signals. Since the highly sensitive to the initial condition of a system and to the variation of a parameter, and chaotic trajectory is so unpredictable. As a result we obtain much higher security. The higher dimensional of the algorithm is used to enhance the key space and security of the algorithm. The security analysis of the algorithm is given. The experiments show that the algorithm has the characteristic of sensitive to initial condition, high key space pixel distribution uniformity and the algorithm will not break in chosen/known-plaintext attacks-In recent years, a large number of discrete chaotic cryptographic algorithms have been proposed.
