Abstract
A method for sharing a digital key associated with a vehicle by a cascaded key delegation system includes issuing, by a requestor device, a public key certificate to an initial delegator device that is part of a cloud delegation service. The public key certificate enables the initial delegator device to grant delegation rights the vehicle. The method also includes issuing, by the initial delegator, an intermediate public key certificate to a subsequent delegator that is part of the cloud delegation service. The intermediate public key certificate grants the delegation rights to the subsequent delegator.
