  A new method for secure information transmission based on generalized
synchronization is proposed. The principal advantage of it is a remarkable
stability to noise. To reveal this peculiarity of the proposed method the
effectiveness of the detection of the information signal from the transmitted
one in the presence of noise in the communication channel is examined both for
the proposed scheme and for the schemes of chaotic communication known already.
The main ideas of the proposed method are illustrated by the example of coupled
R\"ossler systems used both transmitter and receiver.
