Abstract
Methods for exchanging a predecessor domain registrar for the authentication and configuration of digital certificates of IoT devices with a new registrar. The predecessor registrar and the devices are stored using a blockchain. The method may include: determining by the predecessor the number of nearby attestations needed; entering the new registrar into the blockchain; gathering the attestations of the devices using the new registrar; checking whether the new registrar fulfills the defined number; accepting the technical installation with the new registrar as authentication and configuration entity for the devices; sending voucher requests to the new registrar; forwarding the voucher requests to an authorization authority; checking whether the respective device belongs to the new registrar; and if so, issuing a voucher for the corresponding device using the authorization authority and sending the voucher to the corresponding device.
