Speech encryption is becoming more and more essential as the increasing importance of multimedia applications and mobile telecommunications. However, multimedia encryption and decryption are often computationally demanding and unpractical for power-constrained devices and narrow bandwidth environments. In this paper an encryption scheme for AM-WB ITU-T G. 722.2 speech based Arnold cat Map is presented analyzed and evaluated using objective and subjective tests for the 8 modes of the AMR-WB ITU-T G.722.2. Simulation results show that AMR-WB ITU-T G.722.2 based Arnold cat Map encryption is very efficient since the encrypted speech is similar to a white noise. The perceptual evaluation of speech quality (PESQ) and enhanced modified bark spectral distortion (EMBSD) tests for speech speech extracted from TIMIT database confirm the efficiency of the presented scheme.
