1. A system comprising:
a processor; and
a memory communicatively coupled to the processor and storing computer-executable instructions that, when executed by the processor, perform operations comprising:
providing, by a cyber key device, an access control change instruction to an access configuration controller of an asset, the access control change instruction being signed by a private cryptographic key stored by the cyber key device, the private cryptographic key being secured using a trusted environment mechanism of the cyber key device; and
based on the access control change instruction, receiving, by the cyber key device, access to a first access authorization record for the asset, the first access authorization record being stored in a storage system secured by the access configuration controller and defining credentials authorizing access to the asset, the access configuration controller storing a public cryptographic key controlling access to the first access authorization record as an unalterable memory record.
