发明名称 Secure field-programmable gate array (FPGA) architecture
摘要 <p>A method and system for configuring a field-programmable gate array (FPGA) includes receiving an encrypted FPGA load-decryption key at an FPGA from a remote key-storage device. The remote key-storage device may be external to and operatively connected with the FPGA. The encrypted FPGA load-decryption key is decrypted using a session key, which may be stored at both the FPGA and the remote key-storage device. Encrypted FPGA-configuration data is received at the FPGA, and decrypted and authenticated using the decrypted FPGA load-decryption key. The decryption of the FPGA-configuration data may indicate a cryptographic state associated with the FPGA-configuration data, which may be used in recurring authentication of the FPGA-configuration data. For recurring authentication, a challenge message may be received at the FPGA from an authentication device, which may be encrypted using the cryptographic state and the session key to generate a response message. The response message may then be sent to the authentication device to determine authenticity of the FPGA-configuration data.</p>
