Abstract
The present disclosure provides systems and methods for improving provision of secret data on programmable devices. An appliance receives physical unclonable function (PUF) data pertaining to an integrated circuit. Secret data is provided to the appliance from a secret vault. Public and private PUF keys are derived based upon the PUF data. Further, ephemeral public and private keys are derived by the appliance. The public and private PUF keys, along with the ephemeral public and private keys are used to establish a secure channel for programming the secret data on the programmable device.
