Network-layer onboarding of an Internet of Things (IoT) device is the provisioning of network credentials to that device. Network credentials are needed so that only authorized devices can connect to and use an organization’s networks. In the past, established approaches to network-layer onboarding for IoT devices have had some challenges:
- Using the same pre-shared network credential for every device is the simplest approach, but it does not identify each device, nor does it give devices a way to verify they are connecting to the correct network.
- Manually provisioning a unique network credential for each device often makes the onboarding process complex, resource intensive, error prone, and insecure.
- Having manufacturers assign a unique network credential to each device during the manufacturing process is expensive and inefficient.
