Abstract

Method of performing a challenge-response process, comprising, in this sequence, the steps of a) providing a first challenge-response pair (50) on a source device (10), assigned to a responding device (30); b) loading the first challenge-response pair (50) from the source device (10) to a challenging device (20), while the source device (10) is operationally connected to the challenging device (20); c) performing a challenge-response process between the challenging device (20) and the responding devices (30) to which the first challenge-response pair (50) is assigned, d) loading one or more second challenge-response pairs (50) from a source device (10) to the challenging device (20), while the source device (10) is operationally connected to the challenging device (20), wherein the step of loading the first challenge-response pair (50) from the source device (10) to a challenging device (20) is performed before the challenging device (20) has received any information from one of the responding devices (30), to which the first challenge-response pair (50) is assigned.
