Abstract
A cryptographic system () and methodology executable within the cryptographic system () enable the use of a programmable logic device PLD () in a single chip cryptographic design flow for secure cryptographic services. Methodology for secure configuration of the PLD () within a cryptographic systementails secure configuration and authentication (), functional verification (), configuration key reload capability (), traffic key load capability () using a split key technique, isolation between command and key fill domains for secure key fill () of key material, redundant system instantiation (), and high speed comparison for secure operation.
