Abstract
Methods and systems for secured configuration data for a programmable device. One or more memory devices store configuration data that includes one or more configuration bitstreams and associated authentication tags for each configuration bitstream. Each authentication tag is created using the associated configuration bitstream. A programmable device operably connected to the one or more memory devices receives one of the configuration bitstreams. The programmable device uses the associated authentication tag of the configuration bitstream to verify that the configuration bitstream is authentic. The programmable device loads the configuration bitstream if the one of the configuration bitstream is authentic, or may discard it otherwise.
