OBFUSCATING COMPUTER PROGRAM CODE

摘要

A computer-implemented method of tamper-protecting a computer program, the method comprising: processing an input representation of the computer program to identify a function call for causing a data processing system to continue execution of the computer program at a predetermined entry point memory address when said computer program is executed by a data processing system; replacing the identified function call with a modified function call, wherein the modified function call includes an algebraic expression for causing the data processing system to compute the entry point memory address when said computer program is executed by the data processing system.
