Abstract:
The present invention relates to a method for obtaining a PIN validation signal in a data processing unit, the method including the steps of receiving a PIN in the data processing unit, submitting it to a first portable object for verifying it and obtaining a validation signal. The method further includes the steps of catching or receiving an entered PIN directly in said first portable object for verifying it; transmitting a fake PIN to the data processing unit, the fake PIN being seen by the data processing unit as a PIN to submit to the first portable object for verifying it, and returning a validation signal in case the entered PIN is verified successfully in the first portable object. The invention relates also to corresponding system and secure portable object.
