The present disclosure is directed to managing the operation of devices using identity-based cryptography. These techniques may include provisioning a master public key to each system that will communicate with a medical device using device-identifier specific cryptography. A master secret key is provisioned in a trusted processor of the medical device, and the medical device provisions its own device identifier-specific secret key using the master secret key. This setup facilitates several management features, including automatic initial configuration, signed logging, signed backup files, and secure binding of medication containers to the medical device.
