Abstract: The invention provides a method for providing a strong link between a Subject and a cryptographic public/private key pair. The proposed Subject device and key distribution algorithm is less prone to man-in-the middle attacks as comparable known algorithms, thereby inherently strengthening the trustworthiness of any digital signature made with a private key distributed to a user in accordance with the proposed method. The invention additionally enables distribution of authentication factors over unsecure channels and reducing the need of sensitive information transmission by at the same time augmenting security for finally associating a generated public/private key pair to a Subject and using it for signature creation purposes.

Abstract: The invention relates to a method for operating a motor vehicle (1) which has at least one electric machine (7) which can be/is operatively connected to at least one driven wheel (6) of the motor vehicle (1), and a safety device (13) which is assigned to a driven wheel (6), is independent of the electric machine (7) and when necessary applies a positive or negative torque to the driven wheel (6), wherein the electric machine (7) is operated by an inverter (8). There is provision that the inverter (8) is monitored for incorrectly set torques, and that the safety device (13) is actuated as a function of a detected incorrect torque.
