Abstract: The method for authentication and electronic signature is of the private-key, challenge and response type between a user requesting an authorisation (for a specific transaction, or for access to particular resources), via, for example, a smart card (1) and a controller -check terminal (2)-supplying the authorisation. To increase security of the authorisation or authentication operations, the smart card (1) comprises a chaotic generator (23) generating user's acknowledgement code, which is compared with a comparison code generated by the check terminal (2) using a chaotic generator (30) which is the same.
