device birth certificate

Credentials that a device needs in order to establish communications with and be authenticated by the network onboarding component. Device bootstrapping credentials are typically installed on the device during manufacturing, and they must already be on the device before it initiates the network-layer onboarding process. The device bootstrapping credentials are authoritative credentials that are unique to the device and independent of context; they are sometimes referred to as the device birth certificate. The device bootstrapping credentials always include some sort of secret (e.g., a private or secret pre-shared key), which the device will use to authenticate itself to the network onboarding component and to establish a secure communications channel with the network onboarding component.
