Abstract
A program generation method includes extracting a control flow that represents a call/return relationship between functions as well as extracting the functions themselves from a program code, determining an importance of the extracted functions; and inserting an instruction into the program code, to properly perform the control flow based on the importance of the extracted functions. Overhead that occurs during an execution of the program execution is reducible by using control flow integrity (CFI) technique that does not depend on domains.
