Embodiments of the invention relates to utilization of Return Oriented Programming (ROP) for a non-malicious purpose i.e. code obfuscation to improve security. Program code that is associated with a designated function of sensitive nature may be hidden by creating a ROP code that performs the designated function of the original (unobsfuscated) code and constructing a ROP payload that can be loaded to execute the ROP code. The original code may be replaced by a spurious code unrelated to the designated function, and a control flow instruction is provided to load the ROP payload to execute the ROP code. |
