Digital certificates are signed by a server's private key and installed at lock controllers that restrict access to physical resources. The server's public key is distributed to lock controllers and to wireless mobile devices operated by users who are given access to primary locks which secure access to physical resources, and secondary locks, which retain the primary locks within operable vicinity to the physical resources. Additionally, tertiary locks may secure access to internal components of the primary or secondary locks. When a wireless mobile device enters the vicinity of a lock controller, the digital certificate of the lock controller is used as the basis for encrypted communications between the wireless mobile device and the lock controller. Wireless mobile devices may be used to gather evidence of integrity of the locks after use. Lock controllers may be powered by energy harvesting devices.
