Abstract
A secure mechanism for adding network devices uses an unsecure guest network and a secure network both coupled to a secure hub. When an unknown device is introduced, it is initially connected to the guest network and can only communicate with the hub and with a wide area network (WAN). The unknown device is prohibited from communicating with the secure network and any device connected to the secure network. The unknown device provides credentials to the hub, which are verified with a secure database, such as a blockchain ledger, that provides manufacturer device information and certification. Upon authentication, the hub permits the identified device to connect to the secure network. The hub may also configure the now identified device for security and operational parameters. The hub may also retrieve network traffic pattern information from the secure database and use such information to monitor normal expected activity from the identified device.
