摘要： A program generation apparatus generates an obfuscated program difficult to analyze from outside and a program execution apparatus executes the program. The program generation apparatus includes an acquisition unit that acquires a 1st program including one or more instructions, the 1st program causing a process by executing the instructions in a predetermined order to obtain a result; a generation unit that generates a 2nd program based on the 1st program; and an output unit that outputs the 2nd program. The 2nd program causes a process that is different from the process caused by the 1st program and varies according to current information determined at execution of the 2nd program in order to obtain a result identical to the result of the 1st program.

摘要： An obfuscation device includes a first instruction generating unit, for each of a first process and a second process, which generates an initialization instruction for securing a management area for managing identification information indicating an instruction block that should be executed next so as to proceed with the process. Further, a second instruction generating unit generates a selection instruction (i) to make a first selection selecting a process that should be proceeded out of the first process and the second process, (ii) to make a second selection selecting an instruction block indicated by the identification information managed in the management area as an instruction block that should be executed for proceeding with the process selected by the first selection, and (iii) to cause the execution device to execute the instruction block selected by the second selection, and stores the selection instruction in a storage unit.

摘要： A program conversion device generates a program by obfuscating an original program, and generates and encrypts conversion parameters for inverse conversion of the obfuscated program. The program conversion device distributes the obfuscated program together with the encrypted conversion parameters. To execute the obfuscated program, a device having a high security level decrypts the encrypted parameters by using a decryption key stored in advance, applies inverse conversion to the obfuscated program by using the decrypted conversion parameters, and executes the program resulting from the inverse conversion. A device having a low security level executes the obfuscated program without any inverse conversion.
