Abstract
A disclosed device includes a verification unit which performs a data verification of chip design data, an obtaining unit which obtains encryption IP and a verification result output unit which outputs a result of the data verification. The chip design data is designed by using the box IP, the box IP being data which can be disclosed to a chip designer in hardware IP. The encryption IP is the IP including part or all of data of the hardware IP being encrypted. The verification unit decrypts the encryption IP to the hardware IP and replaces the box IP of the chip design data with the decrypted hardware IP so as to perform the data verification, in the storage area such as RAM where storage data is hidden from outside.
