1. A method for managing a device in a vehicle, comprising:
receiving a device registration request for the device;
evaluating a global revocation list that includes a plurality of unique identifiers (IDs) associated with a plurality of certificates;
determining whether a first unique identifier (ID) associated with a first certificate is valid based on a length of time for the first certificate;
communicating a signed version of the first certificate to authorize a session for the device;
revoking the first certificate using the first unique ID;
based on revoking the first certificate, adding the first certificate to the global revocation list;
determining that the first certificate was revoked in error; and
based on determining that the first certificate was revoked in error, enabling the first certificate by removing the first certificate from the global revocation list,
wherein short-lived certificates having shorter time intervals and long-lived certificates having longer time intervals share a same unique ID.
