Selective Encryption of MP3 Compression

paper presents selective encryption technique for the audio which is applied at the time of compression. Here, Advanced Encryption Standard (AES) encryption is applied on the quantized audio data which is performed before the Huffman's entropy coding. Experimental results demonstrate that AES encryption technique provides high security against cryptographies attacks. Here, we have applied the AES encryption technique to different audio files and its utility in the real time systems. The selective technique will save the computational time with the provision of providing security on the audio data. Keywords-AES; MP3; FFT; MDCT; Selective Encryption.
