Abstract

For audio distribution over the network, a secure audio compression format is required. In this paper a novel encryption scheme with low computational complexity is proposed to achieve security level for Advanced Audio Coding (AAC). In this scheme, the modular multiplication and circularly shifts are used to encrypt the selected quantized spectral coefficients and scale factors in the AAC encoding process. The proposed algorithm used chaos theory to generate the necessary random key for audio encryption. The Experimental results show that the encryption algorithms provide good audible distortion because each frame is encrypted by using different key. The proposed algorithms have very large key space and it's sensitive to any modification in the secret key. The proposed algorithms are strong against most attacks and have a high security which is due to combination of the quantized spectral coefficients encryption algorithm and the scale factors encryption algorithm depending on the characteristics of the chaotic system and it is suitable for transmit audio signal in secure way.
