Abstract

In one embodiment, a method for trusted booting of a cryptographic processor system is disclosed. Default image(s) is loaded into a field-programmable logic chip or circuit (FPLC). The default image(s) cannot perform cryptographic processing, but can perform a first algorithm that is unclassified. A processor, internal or external to the FPLC, can be used with the default image. A multi-layer or multi-part key has portions stored in two different places. A protected image is decrypted with the multi-layer key using the first algorithm and loaded into the FPLC. Cryptographic processing is performed using a second algorithm classified by the government.
