A method of encryption for embedding secret information in the spatial and frequency domains of a cover audio signal is described. The method permutes the secret data according to the pseudorandom sequence, generated through pseudorandom sequence generator. The permuted data is then broken into blocks of 128 bits and further encrypted using the Logistic map whose initial value is derived from 128-bits external key. The secret key is modified after encrypting each block. The encryption of each block is key dependent and cryptosystem is further made robust against any reasonable attack by using the feedback technique. The secure data is further embedded in the audio signal in both frequency and time domains and the results have been analyzed for both the cases.
