Performance Analysis of Using G.723.1's High-rate Codes to Hiding Information in Packed Communication System

In recent years,a growing number of chaos encryption algorithms based on chaos theory have been proposed, many of them fundamentally flawed by a lack of robustness and security.In this paper,we propose a novel feedback for the features of G.723.1's high-rate codes to achieve an approach that hides the information in chaos-based secure com- munication system by sending information in the less significant bytes of the coded audio data.The result of experiment proves that the system mentioned in literature[1]is effective and secure.
