Hi,

We have documented the Provisioning process and API in the nRF5 SDK for Mesh documentation on Infocenter. The message sequence chart shows the provisioning process for both nodes, while separate sections below describe the full provisioning sequence for provisioner and for provisionee. In particular, what you ask for is the provisionee Step 5: Authenticating the provisioning procedure.

Private and public keys are generated on both devices, and provided when initializing a provisioning context structure with nrf_mesh_prov_init(). This is needed both for provisioner and for provisionee, and the keys are used (in each end) together with the OOB data, as part of the provisioning process. The details are then handled by our mesh stack when you use the provisioning API as described in the "Provisioning process and API" documentation mentioned in the above paragraph.

Regards,
Terje
