Abstract
Decryption keys used in decrypting encrypted configuration data for a programmable logic device are erased following decryption of encrypted configuration data. A self-erasing key memory delivers a decryption key to a programmable logic device and then automatically erases itself. The keys are then no longer available outside the programmable logic device.
