Abstract
The invention relates to a method of performing user and data authentication over a client (22) in communication via a network (14) with a server infrastructure (16).

The method comprises a user authentication step which includes displaying by the card reader (24) an authentication context, controlling the card reader to request the user for signature approval, and, in the case of signature approval, submitting a challenge, if required together with context data, or data derived therefrom to the smart card (26) for signing. The method further comprises a data authentication step which includes displaying by the card reader (24) the data to be authenticated, controlling the card reader (24) to request the user for signature approval, and, in the case of signature approval, submitting the data to be authenticated, or data derived therefrom, to the smart card (26) for signing.
