Abstract
A system and method for preventing use of invalid digital certificates is disclosed. The method comprises receiving, in a validation service from a requesting entity, a cryptographic asset and a request to evaluate the cryptographic asset, the cryptographic asset uniquely assigned to one of the plurality of devices by an associated one of the commercially distinct entities, the request comprising the cryptographic asset, determining an evaluation state of the cryptographic asset at least in part from a database derived from a plurality of public keys currently assigned to the plurality of devices and previously received by the validation service, determining a disposition of the cryptographic asset according to a disposition policy associated with the determined evaluation state and the device and effecting the determined disposition of the cryptographic asset.
