The Realization of Chaos Real-time Encryption in the Process of Audio Signal High Rate Sampling
-
Abstract
This paper proposes a kind of algorithm which combination of XOR and cyclic shift,a dual-scrambling chaotic encryption via researching the real-time encrypt in the process of audio signal high rate sampling,to encrypt and cover the information of high sampling rate audio signal.Encryption sequence and cyclic shift sequence are generated by chaotic system;the whole process was verified in the digital signal processor(DSP) platform.This method is computing speed and high security,so it can be easily used in embedded systems.
