Özet: Speech encryption is becoming increasingly important as the increasing relevance of multimedia applications such as video conference and news broadcasting. In this paper, we investigate the encryption and decryption techniques for voice signals for Adaptive Multirate Wideband (AMR-WB) G.722.2 speech codec. We applied the Advanced Encryption Standard (AES) encryption and decryption algorithm with output feedback (OFB) mode to the standard AMR-WB ITU-T G.722.2. Two modes from G.722.2 were selected for simulation tests, modes 2 and 8. An efficient speech cryptosystem based AES-OFB has been presented analyzed and evaluated using several tests. Security analysis and experimental results show that this cryptosystem can be used in practical applications in wideband with the standard AMR-WB G.722.2.
