| description | PROBLEM TO BE SOLVED: To solve such a problem that it is impossible to sufficiently enhance security for stored concealment target information in a conventional semiconductor device.SOLUTION: A semiconductor device has a unique code UC specific to the device, and generates unique code correspondence information DI on the basis of the unique code UC. The semiconductor device has a storage area 12 which stores specific information HF2 encrypting concealment target information HF1 in an area associated with the unique code correspondence information DI, and generates the concealment target information HF1 by decrypting the specific information HF2 read out from the storage area 12 by using the unique code correspondence information DI. |
