Abstract :
This paper presents a new secure variant of ADPCM encoders that are adopted by the CCITT as Adaptive Differential Pulse Code Modulation. This version provides encryption and decryption of voice simultaneously with operations ADPCM encoding and decoding. The evaluation of the scheme showed better performance in terms of speed and security.
