Provisioning control apparatus and method for provisioning electronic components or devices
A provisioning control apparatus is configured to be coupled to a provisioning equipment server electrically connectable with one or more electronic devices for provisioning the electronic devices with security sensitive provisioning data. The provisioning control apparatus includes a processor configured to generate a group context for creating a group of provisioning control apparatuses. The processor is further configured to generate the security sensitive provisioning data based on the group context. The provisioning control apparatus includes a communication interface configured to provide the security sensitive provisioning data to the provisioning equipment server. The communication interface is configured to provide the group context to a security server for generating a proxy provisioning control apparatus on the security server. The proxy provisioning control apparatus is configured to provide the group context to a first further provisioning control apparatus for enrolling the first further provisioning control apparatus for the group of provisioning control apparatuses. The first further provisioning control apparatus is configured to be coupled to the provisioning equipment server.
