Abstract
A method for protecting a dynamically reconfigurable computing system includes generating an encoding key and passing the encoding key, through a system level bus, to at least one field programmable logic device and to a function library included within the system. The function library contains a plurality of functions for selective programming into the at least one field programmable logic device. A lock is generated so as to prevent external resources with respect to the system from accessing the encoding key during the passing thereof.
