Abstract
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.
