Device factory certificates

A factory certificate is used to identify a device when initially deployed at the customer site and can then request its operational certificate from a customer-selected certificate authority (CA). The device can then use its operational certificate to establish secure connections in the network and be trusted for the intended operation. 

The device maker prepares devices with OS, firmware, and so on, and connects to a factory CA for each device to obtain a unique certificate of long validity. Multiple certificate enrollment interfaces are supported by Nexus' Smart ID IoT solution.
