A Novel Approach for User Authentication to Industrial Components Using QR Codes

This paper presents a novel approach for a secure user authentication to industrial components using QR codes and time based one-time passwords - the QR login. First, common requirements for a secured communication in an industrial environment will be presented. Second, the comparison of different authentication techniques with focus on one-time passwords will be given. Third, a new model for user authentication with QR codes will be presented. Additionally, a procedure for generating time based one-time passwords is shown. Finally, the presented approach is compared to other popular authentication techniques with an analysis in terms of security, deploy ability and usability.
