Scenario 1.1: Programmable smart devices, direct connection


In this scenario, the device is burned with its unique device triple authentication keys, which can be obtained through cloud registration, before it leaves the factory. The scenario provides stronger security but lower operability due to the demand of the burning of the unique device authentication keys during manufacturing.

Procedure

  1. Pre-register the device to obtain its device triple (productKey, deviceKey, and deviceSecret).

  2. For each individual device, burn its firmware with the unique device triple before leaving the factory.
