Abstract
The use of multimedia data such as compressed audio urge for the need of secure transmission without compromising the audio quality. As there is a tremendous growth of digital data, the issue of security raises, which demands for developing of more advance cryptography techniques. Cryptography is a process that disarranges the information by rearranging and topping the content which makes the original content unreadable except the only person who knows the process of rearranging it. Encryption is a process of converting some data from its original form to encrypted form, practically that cannot understandable by unauthorized user. Decryption is a process of obtaining back the original data from encrypted form. In this paper more secure and fewer complex methods are studied which reduces the time complexity of encrypting and decrypting the audio file and a technique based on partial encryption is proposed where only the header of the audio file is encrypted which results in low time complexity. The techniques used are based on selective encryption, LSFR, Fast Fourier Transform, chaotic system.
