Abstract :
In this paper, we propose an Hinfin synchronizer for chaotic secure communication systems based on the robust control theory. The free parameter in the decrypter is designed to improve the robust stability of the cryptosystem with respect to delays in the transmission line. Moreover, the security level of the proposed system is checked by using the error function attack
