Original Abstract Submitted

A method for controlling access to a motor vehicle includes the steps of receiving a tracking request for a new digital key for a motor vehicle, wherein the new digital key is included in a chain of digital keys that have been created from one another, and wherein the tracking request includes a chain of attestation packages that are assigned to the digital keys in pairs; determining that a digital key to which one of the attestation packages of the chain is assigned has already been authenticated with respect to the motor vehicle; removing from the chain an attestation package that is assigned to a digital key that precedes the determined key in the chain; and providing a tracking response with at least one remaining attestation package.
