A Survey on Speech Encryption Using Chaos Map

Due to the ease of compromising communication channels by attackers, Wireless communications confront considerable challenges in having high security. As a result, ongoing efforts are to provide a practical strategy to ensure robust wireless communication security. Network interferences like reflection regularly affect speech signals, making them vulnerable to security risks. Different techniques for encrypting speech signals have already been proposed. This paper, based on chaotic maps, demonstrates various techniques of speech encryption and decryption. Analog and digital audio algorithms were discussed, displayed, and compared, illustrating the drawbacks and essential features. Different audio and digital proposed methods of speech encryption utilizing chaotic maps have been discussed. These methods demonstrated conducting in quasi-random manner, unpredictability, and significant sensitivity to beginning conditions.
