Due to great progress in wireless communication and the existence of public channel, through which the information transferred among users, the problem related to information security increased, especially the eavesdropping and attacking of these information. These facts required the increase of the security levels of the used cryptosystems techniques in order to prevent the attacking of transmitted information, Based on chaotic maps, this paper provides a new proposed speech scrambling system based on using a hybrid use of different chaotic maps Logistic and Henon. Each chaotic map will generate key that will be used in speech scrambling. the comparison of the system with normal speech scrambler based on using only one chaotic map. Shows good level of security.
