Abstract
Devices, systems, and methods for preparing an electronic lock controller to obtain a digital certificate that verifies authenticity of the electronic lock controller are provided. The method involves physically marking an electronic lock controller with a mark containing digitally signed lock information. The digitally signed lock information includes a hardware identifier, and is digitally signed at a server using a private key of the server. The method further involves loading the electronic lock controller with self-provisioning instructions to cause the electronic lock controller to obtain a digital certificate that includes the public key of the electronic lock controller and the hardware identifier, the digital certificate having been signed by a private key of the server.
