Me­thods of User Au­then­ti­ca­ti­on (Me­tho­den der Be­nut­zer-Au­then­ti­sie­rung)

In this cour­se we consider different types of entity authentication. Starting with passwords, that we all use on a daily basis, we will see how they are utilized, why they are easy to guess, and how we can improve their security. Afterwards, we will look at different alternatives like one-time passwords, graphical passwords (e.g., Android Lock Patterns or Windows Picture Passwords), security tokens (e.g., Yu­bi­Key or RSA SecurID), or biometric schemes (e.g., Face recognition or Brain–computer interfaces), and learn their functionality together with their assets and drawbacks.
