摘要

The invention relates to a method for an enhanced level of authentication related to a software client application within a client computing device, wherein the client computing device comprises a subscriber identity module entity comprising a subscriber identity module toolkit as well as a subscriber identity module applet, wherein the subscriber identity module toolkit comprises a number of commands to be executed by the client computing device, wherein the software client application comprises an authentication-related command and/or module requiring an information provided from a user of the client computing device, wherein the method comprises the following steps:-- in a first step, the authentication-related command and/or module is invoked by the software client application, and a first group of application protocol data units exchanged between the client computing device and the subscriber identity module entity,-- in a second step, subsequent to the first step, the subscriber identity module applet is triggered - by means of the first group of application protocol data units - to contact the subscriber identity module toolkit and/or to trigger a command of the subscriber identity module toolkit,-- in a third step, subsequent to the second step, a second group of application protocol data units are exchanged between the client computing device and the subscriber identity module entity, wherein the subscriber identity module toolkit thereby triggers the client computing device to request a user action from the user of the client computing device.
