Abstract
Systems and methods for provisioning secure programmable logic devices (PLDs) are disclosed. An example secure PLD provisioning system includes an external system comprising a processor and a memory and configured to be coupled to a secure PLD through a configuration input/output (I/O) of the secure PLD. The external system is configured to generate a locked PLD comprising the secure PLD based, at least in part, on a request from a secure PLD customer, wherein the request from the secure PLD customer comprises a customer public key; and to provide a secured unlock package for the locked secure PLD. The external system may also be configured to provide an authenticatable key manifest comprising a customer programming key token and a corresponding programming public key associated with the locked secure PLD, wherein the authenticatable key manifest is signed using a programming private key generated by the locked secure PLD.
