Audio Encryption in Handsets
A novel method to encrypt audio (sound) stream of data by applying chaos is discussed. A pair of one-dimensional logistic maps is used for generating a chaotic sequence. The routine tests of encryption are performed and the results are observed. The proposed scheme is then implemented in real time on a mobile phone and the robustness of the idea is established. Encryption process deals with secure transmission of data. The necessity of using encryption in a communication system is to protect the data from being received by persons other than the intended recipient. Thus encryption is an indispensable block in the transmission section of any communication system.
