ABSTRACT:
A system and method have been provided for securely provisioning configuration data in a network-connected integrated circuit device. The method comprises: receiving configuration data addressed to device registers; loading the configuration data in configuration registers; and, locking to prevent the loading of subsequently received configuration data. Locking to prevent the loading of subsequently received configuration data includes the substeps of: establishing at least one locking register having a first address; loading a first lock set in the locking register; and, in response to loading the first lock set in the locking register, preventing the loading of received data in the configuration registers.
