Abstract
A method is described for generating a challenge-response pair in an electric machine as the basis for an authentication. The electric machine has at least one stator and at least one rotor. A voltage signal or current signal which causes induction between the rotor and the stator is generated as the challenge, and a variable which is a function of the caused induction is determined as the response.
