| Zusammenfassung: | A method for generating a challenge-response pair in an electric machine as a basis for an identification or authentication is described, the electric machine having a stator and a rotor, a first alternating voltage between two points of a first defined point pair of the electric machine being applied as a challenge, which causes an induction in the electric machine, a variable dependent on the caused induction being determined as a response. The first alternating voltage has a frequency which is higher than the working frequency of the electric machine. |
