System and method for multi-certificate and certificate authority strategy

摘要

Operations or functions on a device may require an operational certificate to ensure that the user of the device or the device itself is permitted to carry out the operations or functions. A system and a method are provided for providing an operational certificate to a device, whereby the operational certificate is associated with one or more operations of the device. A manufacturing certificate authority, during the manufacture of the device, obtains identity information associated with the device and provides a manufacturing certificate to the device. An operational certificate authority obtains and authenticates at least a portion of the identity information associated with the device from the manufacturing certificate and, if at least the portion of the identity information is authenticated, the operational certificate is provided to the device.
