Abstract:
Method and systems using stateful encryption for non-bypassable FPGA configuration including receiving, at an FPGA, FPGA-configuration data comprising a cryptographic state to initialize a cryptographic state of the FPGA, and decrypting, at the FPGA, the FPGA-configuration data, wherein decrypting the FPGA-configuration data yields at least a second cryptographic state and decrypted FPGA-configuration data. Embodiments can include receiving, at the FPGA, a challenge message, processing, at the FPGA, the challenge message to yield at least a third cryptographic state and a response, and transmitting the response from the FPGA.

Claim (Index 6):
A system comprising:\n a field-programmable gate array (FPGA) configured to receive FPGA-configuration data, the FPGA comprising a decryption unit arranged to decrypt FPGA-configuration data to configure a programmable logic unit of the FPGA; and an authentication device configured to transmit challenge messages to the FPGA and to receive response messages to the challenge messages, wherein the authentication device is further configured to authenticate the response messages by comparing the response messages to expected response messages, wherein the FPGA is configured to process the challenge messages to yield the response messages, and to transmit the response messages to the authentication device.
