    摘要: A program converter (1) converts a program (P) which performs arithmetic addition processing to execute encryption, into a converted program (tP) which performs processing equivalent to the processing of the program (P). The program converter (1) includes: a key data extraction unit (10) which extracts key data from the program (P); an addition table generation unit (11) which generates an addition table from the extracted key data; a conversion table extraction unit (12) which extracts a conversion table from the program (P); a table merger unit (13) which generates a merger table by merging the generated-addition table and the extracted conversion table; a random number generation unit (14) which generates a random number; a table randomization unit (15) which generates a randomized merger table by randomizing the merger table using the generated random number; and a converted-program generation unit (16) which generates the converted program (tP) according to the generated randomized merger table.

    摘要: Provided is a game system in which a plurality of game execution apparatuses, having internal structures different from each other, are capable of proceeding with a game while sharing characteristics of a character appearing in the game. A stationary game apparatus 100 obtains character data from a server apparatus 600, and writes the character data to a memory card 300. The stationary game apparatus 100 executes a stationary game software program stored in a DVD 500, using the character data stored in the memory card 300. A portable game apparatus 200 executes a portable game software program stored in a cartridge 400, using the character data stored in the memory card 300.

    摘要: A theft prevention system capable of preventing theft of a target object by disabling the authorized key of the target object in the case where the authorized key has been stolen. When the authorized key is lost, a mobile telephone instructs a vehicle control device to set a warning mode. On receipt of this warning mode instruction, the vehicle control device sets warning mode, generates an electronic key, and transmits the generated electronic key to the mobile telephone, which receives and stores the electronic key. Once the warning mode is set in the vehicle, locking and unlocking are only possible using the electronic key. If the authorized key is found, the mobile telephone instructs the vehicle control device to set the normal mode. Upon receipt of this normal mode instruction, the vehicle control device sets the normal mode in the vehicle.
