METHOD FOR DETECTING A PROGRAM DATA ATTACK, CAPABLE OF CHECKING THE INTEGRITY OF PROGRAM DATA PATCHED IN A CPU

摘要

PURPOSE: A method for detecting a program data attack is provided to detect a hacker attack by checking the integrity of program data patched in a CPU.;CONSTITUTION: An operation register is initialized in response to an instruction for checking a program data attack(120). The operation register stores the operation result about the function which builds an algorithm. The operation result saved in the operation register and a reference value included in the program data are compared(150). The reference value is the expected operation result when the program data was not attacked from outside.;COPYRIGHT KIPO 2011
