Described herein are complete lifecycle management processes for IoT/M2M devices. In an example, devices are commissioned and de-commissioned in a given system without requiring a user/human administrator. A delegated life-cycle management process is described, wherein devices rely upon a delegatee, which may have more computing and battery resources than the devices, to perform complete or partial lifecycle management operations on behalf of the devices. The delegatee may be a trusted entity that may belong to the same domain as the devices. Further, a Trust Enabling Infrastructure (TEI) is described herein, which may belong to a different trusted domain than the given device and its delegatee.
