Abstract
Methods for updating ephemeral keys on quick boot of a computing device, including determining, by a processor of the computing device, that a power-on transition is from a quick boot and generating, in a secure portion of the processor, a new ephemeral key for use in wrapping one or more encryption keys of a key ring for use in an unsecure portion of the processor in response to the quick boot. The secure portion of the processor may unwrap each of the one or more encryption keys of the key ring with a prior ephemeral key before wrapping the one or more encryption keys with the new ephemeral key.
