PROBLEM TO BE SOLVED: To provide a data processor capable of heightening security of an application program operated on a server device, in providing service using an integrated circuit such as IC, backing up or restoring. SOLUTION: In the case of backing up a SAM unit 9, a back-up package data BPK storing header data HEADER for specifying the back-up system, enciphered application element data APE as a back-up object, and the enciphered set data 512 is output from the SAM unit 9 to a computer 500 and stored. In restoring, a restore package data RPK storing header data HEADER, enciphered application element data APR and the enciphered set data 512 is transferred from the computer 500 to the SAM unit 9. |
