A chaotic communication scheme with a fibre ring inserted in the optical feedback of the transmitter laser as an additional key is proposed under anticipating synchronization.The numerical results show that the key can enhance the communication security effectively.It is theoretically safe for the communication scheme to transmit messages with a frequency beyond the relaxation oscillation frequency.
