In this paper, the encryption improvement via modulation of the fractional-order chaotic oscillators state variables is presented. A network of N-coupled fractional-order Lü chaotic oscillators, is synchronized. A voice message is encrypted, via additive encryption, by using a state variable of the synchronized network. The selected state variable is modulated and used to encrypt the message again. The results are compared.
