Abstract
In one embodiment, a method for operating a field-programmable logic chip or circuit (FPLC) is disclosed. Operation of the FPLC includes a configuration state and a cryptographic processing state. Switching between states is controlled by a state machine. Each state has one or more images. Transferring between states causes some or all images from the other state being overwritten.
