A subprocess of network-layer onboarding. It introduces just enough information to a device and a network onboarding component to enable them to trust one another and establish a secure channel. The trust established between the device and the network onboarding component through bootstrapping may be either mutual or one-way. The introduction within bootstrapping may be performed as an out-of-band (OOB) process requiring human interaction.
