We present a method in which a chaotic signal is used to mask a message securely. It depends on separating the two tasks of synchronizing the chaotic oscillators and encrypting the message. A sporadic drive together with a function f of the ciphertext and response system variables is used to make extraction difficult. We give a choice of f that makes the method similar to a one-time pad, with pseudorandom numbers provided by the chaos.
