PROBLEM TO BE SOLVED: To improve security at the time of calling a function of a DLL (dynamic link library). SOLUTION: A DDL isolation load determination part 205 of a DDL using program execution part 251 instructs load of an encrypted library 105 to a DDL isolation load program execution part 253. The DDL isolation load execution part 253 loads the encrypted library 105 to an isolation area according to the instruction. A DDL calling part 107 of the DLL using program execution part 251 instructs the DLL isolation load program execution part 253 to call a function mounted on a code in the encrypted library 105 loaded to the isolation area. The DLL isolation load program execution part 253 executes the code mounted on the encrypted library 105 in the isolation area according to the instruction, and reports the execution result to the DLL using program execution part 251.
