An apparatus and method for verifying the integrity of firmware of an embedded system is provided. The apparatus for verifying the integrity of firmware of an embedded system includes a target integrity code obtainment unit for obtaining a target integrity code of firmware of the embedded system. A source integrity code obtainment unit obtains a source integrity code of source firmware. An integrity determination unit determines whether integrity of the firmware of the embedded system is maintained, by using the target integrity code and the source integrity code.

An FPGA apparatus and a method for protecting bitstreams are provided. The FPGA apparatus includes: a key storage unit, which is configured to be accessed only from within the FPGA, and having stored therein the encryption/decryption key and the initial key generated by the random number generator; a setting bitstream storage unit, which is an internal non-volatile memory stored with bitstreams for setting authentication and encryption/decryption; and an authentication and encryption/decryption setting unit, which is configured to call the encryption and decryption key and the initial value stored in the key storage unit to store encrypted bitstreams and authentication codes generated as a result of performing encryption on the bitstreams stored in the setting bitstream storage unit in external non-volatile memory, and verity the integrity of the encrypted bitstreams stored in the external non-volatile memory at the time of designing of the FPGA using the encrypted bitstreams.
