A method for program execution in a system including a decryption apparatus that prevents external referencing and an information processing apparatus communicating therewith and accessing first and third storage areas, includes: the decryption apparatus detecting a series of commands from a command group obtained by decrypting at least a portion of a program stored in the first storage area; obfuscating and storing the series of commands to a second storage area storing the decrypted portion and within the first storage area; assigning, when an execution request is received from the information processing apparatus, the third storage area having a capacity equivalent to any one series of commands; and storing to the third storage area, a series of certain commands stored in the second area and obtained by canceling obfuscation of the commands that correspond to the execution request; and the information processing unit executing the series of certain commands. |
