摘要

The proposed method advantageously makes use of a standard HTTP authentication challenge methods in combination with standard encryption algorithms in order to arrive at a new challenge response method which is able to use existing application program interfaces (API) of current operating systems for mobile devices, including iOS developed by Apple Inc., Cupertino, California, United States of America. The proposed method advantageously enables a two factorauthentication applying the protocol HTTPs by using a smart card. This advantageously facilitates a usage of existing PKI infrastructure on mobile devices.
