Abstract
Speech is widely used in our daily life with cell phones and over the Internet, especially for long distance calls. Higher security for transmitting these data is required. Therefore an encryption scheme for the speech signal encryption based on combination of permutation and substitution are proposed in this paper. The permutation process is performed based on permutation key that generated from Game of Life matrix which is a simple cellular automaton, remarkable for its complex behavior. . The substitution performed with mask key that generated from one dimensional cubic and sine chaotic maps. The initial conditions and control parameters for chaotic maps are used as password for the sender and receiver. In order to check the performance of the proposed encryption algorithm , experimental implementation has been done. The results indicate that the encryption system provides encryption speech signal of low residual intelligibility while preserves the good quality of the recovered speech signal. The system has a large key sensitivity because a small change in the secret key causes a large change in the encrypted signal.
