The key manifest comprises one or more verification keys. The digital signature is verified using the public key and the processing device stores the key manifest in a persistent storage component in response to successful verification of the digital signature. The one or more verification keys are utilized in one or more verification operations based on the key manifest being stored in the persistent memory component.
