Abstract: A mechanism for registering a device with an Internet of Things (IoT) edge network is disclosed. The manufacturer of the device stores credentials of the device in a secure storage of the device. The manufacturer also stores the credentials on a public blockchain with sensitive parameters hashed or encrypted. A certifying node accesses the credentials from the public blockchain to establish a secure connection with the device and to verify its credentials. The device sends the credentials to the certifying node, only if the certifying node is able to decrypt a device access parameter from the public blockchain. Upon verifying the credentials of the device, the certifying node issues a digital certificate to the new device and it is stored on a permissioned blockchain within the IoT network. Other nodes in the IoT network may use the digital certificate on the permissioned blockchain for secure communication with the device.
